BUG: 3.6.0 (b1421) - Effect offsets displaying incorrectly

Hi,
I know we have suffered degradation over time with effect offsets in cues, as the 0>359 degree system is at a different resolution to the console's offset resolution...
But now, if I take 12 fixtures and set their offset to 0>330, instead of setting them to 0,30,60,90,120,150, etc... it now says 0, 29,60, 90, 119, 149, 180.... this is incorrect and a new bug.
