Gamebreaking bug with Deadly Resolve

My party members have been experiencing constant crashes whenever they group with me. After experimenting with different gems, I’ve narrowed it down to the issue being caused by the Deadly Resolve support gem combined with any channeling skill. As soon as I fight monsters while my group members are off-screen, they crash.

+1, I'm one of the party members.

How to reproduce the issue:
1. Be off screen from your party members.
2. Channel a skill that has deadly resolve support equipped.
3. Be hit during channelling, triggering deadly resolve.
4. Party members crash.
