The title says it. When a guardian beam is blocked with a shield that is enchanted with reflection, the game crashes. crash-2022-10-13_09.03.49-server.txt

I suffered similar problem, but the shield was Moissanite (via integration with More Gems). My shield is also enchanted with Reflection and I was also hit by a Guardian's beam when the game crashed.

This issue has been patched in newer versions I just need to backport the fix
