probably an update issue but thought id check first Gpass version;
14:59:47: Controller detected
14:59:48: UnderMine, 1.0.1.4 (WINDOWSSTORE/XBOXGAMEPASS)
14:59:50: Successfully attached to UnderMine
14:59:51: player, Script error in line 3: 'Thor.SimulationPlayer:Update+500' is 0 or not a valid address
game version is 1.0.2.10 so assuming version mismatch
Trainer was made for the STEAM version (WINDOWSSTORE/XBOXGAMEPASS not currently supported), but did get a few patches the other day.
steamdb.info/app/656350/patchnotes/
then why does it have a gamepass/ windows version?
So it does, that will teach me to go 48 hours with no sleep...Probably still needs an update or you could try cleaning the data folders.
