Unless you picked the option which gives access to the cheats at the start of the game, then that save is probably a dead end now, yes. If you want to travel around without worries, you must have at least 4 MR, if I remember correctly, anything lower and the clock starts ticking with each trip you take. You get warnings in the form of scenes during travels, and examining yourself gives you some hints of your overall mental status as well.I got to the point where I'm stuck in Europa 4, leaving to any planets will result in ALICE taking over. I've tried boosting MR to 2 with the VR and book, also upgrading the engine but still results the same.
Is there no way to continue anymore? Is my save just fucked now?
There are ways to raise your MR during quests and events, but I don't know if you have access to any where you are now.
