link textHi there. Using 4.12.5, I get a crash whenever I try to create a New Service, Decorator or Task in a Behavior Tree, whether the behavior tree is populated or not.
I had success creating a new service for a behavior tree in a brand new project, so that leads me to believe there’s a conflict with something in my project. I disabled all 3rd party & experimental plug-ins and restarted, hoping that there was a conflict in there somewhere, but I still got the same crash.
Here’s the debug info generated on crash and I’ve attached Report.wer, CrashContent.runtime-xml.
Thanks,
Alec
