I randomly started getting this error when everything had been working fine for months. Literally just played less than a week ago with no issue, then suddenly I start getting this error as soon as I load a game. Nothing has changed since the last time I played so I don't understand why it's all just now happening. It has something to do with mods I believe because the only way I've been able to get rid of it is removing all my mods. But oddly enough it doesn't seem to be any one particular mod. I started putting them back one by one to try and narrow it down and every single one causes the error. So I'm at a loss. Makes no sense why it was working one day and now it isn't.
