Hey there. Was just wondering about some simple ways to edit a save game and add some abilities that will speed up the game for me (after already numerous replays with everything normal) - mainly giving myself telekinesis from the start, maybe crafting and such similar small things, and you just posted this. Great timing, really!
But sadly, it doesn't work for me. You did say it's for steam version, so, that's probably the reason, as my game is GOG release, 188.8.131.520.
But also, in the off chance that is actually not the problem, posting the error message.
Thanks in any case!
