[BUG] Rotating mount lags out people

[mkahvi]

Describe the bug
Rotating mount causes massive lag (in PF1e).

Environment Details
Foundry VTT Version: 0.6.5
Mount Up! Version: 3.0.1

To Reproduce
Steps to reproduce the behavior:
1. Mount up
2. Rotate mount rapidly 360 degrees or more
3. See how you and other players have the whole system lagged out and unresponsive for a long time.

Expected behavior
No lag.

Additional notes
One player lagged out so bad they got disconnected (the lag on their end was taking like 20 seconds longer than on mine, the mount rotating veeery slowly).
