Instance Crash: Offset Chilled Ground Instances + Navira's Oasis

This issue remains unresolved as of 0.4.0b Hotfix 1.
--------------------------------------------------


Previously titled Instance Crash: Trail of Ice Companion + Navira's Oasis


Bug Description
----------------------
The instance crashes and disconnects the player when the player uses Command: Navira's Oasis on multiple Chilled Ground instances that are not in the same position and/or are not the same size. This does not occur 100% of the time.

Most likely, the cause of this is related to the similar bugged interaction between Navira's Oasis and Chilled Ground produced by a tamed beast companion with the Trail of Ice modifier.

Videos of the Bug:
https://youtu.be/oYC_AJ8MJkM - At the start of the video you can see a Navira's Oasis that had been successfully created from a single instance of Chilled Ground. Then the instance crashes when trying to create a Navira's Oasis with two offset instances of Chilled Ground.

https://youtu.be/yf40_SNA9MQ - Navira's Oasis is successfully created from two instances of Chilled Ground that were created in the same position. Then the instance crashes when trying to create a Navira's Oasis with two offset instances of Chilled Ground.

https://youtu.be/rtPNlq-Twk0 - The instance crash bug did not occur with Chilled Ground from Ice Novas. Tested with two instances of Chilled Ground in different sizes and two instances of Chilled Ground in different locations. In each case, each instance of Chilled Ground is converted into its own instance of Navira's Oasis. Hoping that the bug was hotfixed while I wrote this report, I tried using Navira's Oasis on Chilled Ground from a tamed beast companion with Trail of Ice, but the instance crashed.


Expected Behavior
----------------------
1. Both instances of Chilled Ground are converted into Navira's Oasis. This is the behavior that can be observed when the bug does not occur, as shown in the third video listed above (https://youtu.be/rtPNlq-Twk0).
- Alternatively, the nearest instance of Chilled Ground is converted into Navira's Oasis while all other instances remain Chilled Ground and do not convert into Navira's Oasis.
3. The instance does not crash.
4. The player is not disconnected from the server.


Steps to Reproduce the Bug
----------------------
1. Use Frost Bomb twice to collect two Cold Infusions.
2. Create two instances of Chilled Ground by using Ice Nova, moving a short distance, and using Ice Nova again.
3. Use Command: Navira's Oasis while near both instances of Chilled Ground.
5. Instance crashes and you are disconnected from the server.

Below is the original bug report for the specific interaction between Trail of Ice Companion + Navira's Oasis
------------------------------------------------------------------


Bug Description
----------------------
The instance crashes and disconnects the player when the player uses Command: Navira's Oasis on Chilled Ground produced by a tamed beast companion with the Trail of Ice modifier. This does not occur 100% of the time as, occasionally, it is possible for the Chilled Ground to be converted into Navira's Oasis successfully without crashing or being disconnected.

Video of the Bug: https://youtu.be/ez-84tPE4vU


Expected Behavior
----------------------
1. Existing Chilled Ground created by the beast companion is converted into Navira's Oasis.
2. While in combat, the beast companion continues to create Chilled Ground that remains Chilled Ground and does not convert into Navira's Oasis.
3. The instance does not crash.
4. The player is not disconnected from the server.


Steps to Reproduce the Bug
----------------------
1. Use Tame Beast to capture a beast with the Trail of Ice modifier.
2. Summon the beast on a Sorceress with the Disciple of Varashta ascendancy and the Navira's Oasis notable.
3. Walk near enemies to enter combat.
(The beast is now continuously creating Chilled Ground.)
4. Use Command: Navira's Oasis on the Chilled Ground produced by the beast.
5. Instance crashes and you are disconnected from the server.




Context
----------------------
I am playing a support build and the Navira's Oasis skill looks like a good way to buff the defensive power of my allies. The skill can only be used when Chilled Ground is available, so I need a way to create Chilled Ground without the need to use mechanics irrelevant to my support build. My first thought was to cast Frost Bolt as needed, but then I saw that this spell had lost the ability to create Chilled Ground in 0.3.0.

I went through the skills/supports but they all had one or two mechanics that I didn't want to invest in (Frost Nexus [Freeze], Creeping Chill [Power Charges+Crystals], Arctic Howl [Freeze+Talisman], Ice Nova [Infusions], Fangs of Frost [Spears]).

Navira's Embrace seemed liked my best bet as I already had the skill, being a prerequisite for Navira's Oasis, and it creates Chilled Ground when the bubble's life reaches 0. The bubble's life is scaled by my mana, so having as little mana as possible would be the best way to enable this interaction. Unfortunately, I am heavily investing in my mana (Mana before Life), so creating Chilled Ground through this method will only get harder as I continue to level up.

The last option I found was to use a beast with Trail of Ice. Reserving a large percentage of my Spirit to enable this skill is a tough price to pay, but it seems like the most convenient option at this time. Unfortunately, as this bug report states, this method also crashes the instance.
