I had the 4:ItemIdenitfyException, and now it wont let me on. I tried reinstaling, I thought it would work but sadly it didn't. I don't know what you mean by getting rid of the mods? Also, I did download a map which is why (I'm guessing) it made FeralHeart not let me on. I looked at the files, and yes there was some Bonfire files. I deleted them, but that still didnt work. I'm losing hope here and almost nothing else on here is helping me.
