Somehow an EQS query that previously had a gird path generator is broken and wiped blank for me when I reloaded the project the next day. It’s possible I didn’t save something during the last session.
This results in attempts to call the EQS query to never complete. Took a while for me to debug why all of a sudden my working AI was stuck.
I managed to repro it. It’s probably reproducible with even less steps than what I have here.
So you create an EQS query, save it. Close it.
Reopen it. Add some tests. Save it and close it.
Open it again. Delete the main node and then hit ctrl+z to undo deleting it. Save it. Close it. Restart editor. The problem is there.
I think the undo action on deleting the generator node doesn’t properly restore it somehow. Saving after undoing the deletion causes the next run of the editor to have the generator node in a deleted state.
