I was thinking of maximizing my FPS by lowering the game's screen resolution all the way, but it wouldn't open. I got this error message (I couldn't copy and paste it, so here's a screenshot)
When I updated RoR to 2022.12, I found that my mods didn't work. I tried reinstalling them, and that didn't work either. The only mod that did work was the one I downloaded through the in-game repository, the Subaru Impreza.
