I tried to spawn Burgl with console commands now, which seems only possible in Singleplayer and needs 3rd party software.
Sadly after spawning (a new?) Burgl, the game just ends itself when I try to give him the next Chip(its not even a SuperChip). Dialouge options were also a bit weird, so I guess that route does not work at all.
So...back to waiting for a fix or workaround from Obsidian.
