Another day another glitch cheese

While in the Abyssal on my last life doing a multi teleport my game suddenly froze.
I could move in slow motion but all enemies suddenly despawned.
I had no choice but to hard quit,
I returned to find I had "died" with full penalty.

I know the policy is to refund absolutely nothing, but this is truly skeezy.
Continuing to leave this unaddressed is not O.K.
When the game crashes that is the fault of the provider not the player.
Many of us put a value on time. In my case I am very ill and do not like it wasted as I have little left.

Please address this immediately.
This is the last time I intend to use this method to attempt to resolve this issue. I feel failing to do so already shows extreme negligence.

Post edit:
After loading again I found my XP restored and was able to re-enter with the Abyss closed.
There is definitely a serious bug here.
The source is likely due to treating Abyss instances as single fail events.
I don't know why this was chosen and find it counterproductive to a "grind" philosophy.
