basically what it says on the tin. i was in boondollar mansion going through all the wardrobes of stuff when all of a sudden the items inside started automatically going into my inventory and i couldn't put them down- if they were equipables, they would equip and i couldn't unequip them. even the things i had already had in my inventory before the glitch occurred would not leave. i also couldn't interact with any objects anymore- i was able to open the cruxtruder just fine for some reason, even though that happened after, but when i tried to put my pre-punched card in the lathe or click on the punch designix, the ui refused to come up.
Sounds like the game thought you were holding down shift. The log file reveals nothing special.
