Ok i noticed it mainly with Aprosis and it repeats every time i reset him due tweaking stuff on my side.
Once you wipe on Aprosis, and at least one char is in zone remaining FD it crashes the zone and after you log back in the Progress of your robot is fully reset and Kogg is back at his spawn point.
IF you would need now to get back isle 3 incase you had a full wipe you would need to restart the assembly of the robots and activate the jumpers again. Or if you decide to just go further you couldn't you would be stuck on the Isle the crash happened.
