I played through the Steam demofestival and then decided to grab the alpha version. After multiple playthroughs, the following bug occurred:
############################################################################################
ERROR in
action number 1
of <Unknown Event>
for object oEFMindControlled:
Unable to find instance for object index 201535
at gml_Script_crew_move_start
############################################################################################

looking forward to the steam lunch
