I’ll be short. As far as we’ve got with the tests, 4.13 had changed the way MoveToLocation functioned (which probably was for the better but our AI code didn’t work correctly with it at the time. I’m not 100% that was the only issue with the AI in that version, some of the behaviors we seen might’ve been from somewhere else) and the main UI wasn’t showing.
We haven’t got as far as testing the sound with that version since there were other bigger issues (not showing the UI was the main problem and we didn’t had the time to test it further) so I can’t tell if that was an older 4.14 problem or not.
