Hello! Sorry about taking awhile, but I’ll try to send a video and screenshots of the segments of code in question.

I’ve uploaded a small recording and set it up on youtube on a non listed video:

Its somewhat weird because it works most of the time, but I’ve noticed that rarely, if we get an error message somewhere else in the game, say a missing ref or a shader problem, the whole behaviour tree becomes unresponsive since I need the callback from the OnCheck function working. Took a bit to realize that ceased to be happening, and why my NPCs were acting up.

As for the questions: it usually happens after the behaviour tree is re-enabled, yes. Hoping that can give enough hints as to what is happening hahaha!

Cheers!

Edit: put the screenshots as attachments
