shift key not decreasing rotation increment too 5/15 degrees.

[123nick]

for some reason, im using alot of mods and the shift button just is not working in editor. holding it while pressing W, A, S, or D, will not decrease angle increment size too 5 degrees, like it should, or 15 degrees or whatever it was. it looks like it increments 5/15 degrees for a second, then rotates the full 90 degrees. i dont remember adding any new mods, except hangar grid, but that mod does not modify angle increments at all. is it editor extensions?
