Maybe a little bit too late but I gained access to the debug console in divinity 2, budget version 1.3.15.112:
debug console Now I'm caught in there and can't get out.
As a workaround I execute a console command, create a savegame, restart the game and load the savegame.
Maybe this will become usefull some day.
Up to now there is a problem with unknown parameters for example for the "summon" and the
"give_all_of_type" command.
