Molten Vault bug - Lava Blocking Rewards.

Quick Summary:
Ran a T16 Map in Molten Vault. Cleared the place, and the entrance
to Abyssal Depths spawned at the foot of the lava sluice.
due to there being lava from the bossfight, it is inaccessible, blocking entrance to the Abyssal Depths aswell as rewards.

dropping down to the arena puts me on top of the lava, which instantly pushes my character to where there is no lava.
