I have been on the Little Crusaders Beta Version for a few days now, and I have been attempting to switch back to the main version of the game, however, it will not let me because this error message pops up:
So I cannot currently switch back to the main branch, I am stuck in the Little Crusaders beta.
Was able to force close Steam and got it to run through administrator. I re downloaded Tower Unite and had them write over the old files, and it seems to have fixed.
