Sorry to bother but my game seems to be playing at double the normal speed and it only seems to happen when I have this mod installed. If anyone knows the solution I would appreciate the help. Thank you!
Are you launching it from steam? Launching it from steam doesn't use the executable. I suggest you copy the nuclear throne folder and rename it to the mod, delete the nuclear throne executable, and use the ultra mod exe file instead. You can even put it in the steam library as a non steam game.
