Angles are not clamped within -360/360, and at some point entity will just stop visually rotating (will stay at same spot).
Found that those entities stop rotation (only visual) when some angle value is above 32768 or below -32768 on linux, and -16777216/16777216 (=32768*512) on windows, at least on my computer and on my dediacted server.
