Pushing verse changes after editing a npc_behavior class crashes Fortnite

Summary

The title says it. Editing a npc_behavior class, compiling the verse code and pushing verse changes will sometimes crash Fortnite. Not UEFN.

I can confirm it’s tied to npc_behavior as this used to happen when I was building bosses in a map of mine, stopped happening when I finished making them and is now back after 3-4 months while I’m trying to build another boss.
