Just to report my sightings
I have had issues with whole editor freezing when doing playtesting (for very long time). Only sounds keep playing and need to force the exe down without getting any visible errors in rpt.
Noticed now that while using “Move To” in behaviour tree with “Project Goal Location” turned off, I have got that freeze much much more. Currently searching my blueprints/trees through to find remaining move commands without that and so far no freezes. Also been adding “does path exist” checks. Its looks very strongly that there is something unstable with “move to” if that setting is turned off.
I am using dynamic nav mesh generated around invokers. There might not be nav mesh always to reach the move to destination.
