I've been using Playmaker for a while in my project. I'm experiencing weird issue right now. After building a project - all references to prefabs with FSM are missing.
I have Scriptable object that represents level configuration. In this object I have references to level objects. It's a gameobject with FSM on it. After building this reference are missing objects.
The only solution I found so far - disable auto-preprocessing FSMs on build. I do it manually - fix links and build my game after.
