Snipe causes crash on unique enemies in temple

The ability "Snipe" causes crashes for both players when sniping a unique boss below 50% hp in the league temple.
It happened on multiple consecutive occasion on the commander's quarter boss (when sniping upon loading back in) and happened on the golden forge boss as well.

Are you sure it's related to the boss and hp?

We had the same issue and it was caused by sniping into a room from outside it.

Since we found that out it hasn't crashed again despite frequent use of snipe.

I was definitely inside the room when crashing. I can also snipe at the beginning of the fight without issues.

I'm not sure the threshold is 50%, could be lower.

The first time I crashed, I logged back in and sniped again and instantly crashed as well. I repeated this once more before realizing what was happening.
