Hi all of a sudden my rotating objects/brushes/models/etc will no longer rotate. I dont know what I did to turn rotation off, but If anyone knows how to fix and or turn it back on, youll will save me!

I fixed it, my radiant bugged out and thought my grid size when ever i rotated was 1600 units. So i went on the 2d grid and just selected 1 unit and it all went back to normal
