I have a question, is it possable to roback my charter to a previous state cause i have had the ??? item glitch and as far as im aware its un fixable so i just delete the ??? items and start from scratch, but now its getting annoying and im just curious if you could role back my charter and if so what do you need, i couldnt take a screenshot before cause it was unexpected and i didnt after cause i didnt see the reason to after the damage was done, anyway please help me if you can.
