Avatars on some boats lean far out over boat edges for balancing against wind/sail pressure. They are moved side to side as boats tack and jibe. This has ceased to work properly (vs Main Grid) in the H4 sims on Beta. Avatars are not changing position on command. I demonstrated this issue to Sidewinder, Andrew and Simon Linden during the Jan 24 bug review meeting. This symptom once appeared on the Main Grid and was fixed. Time frame Oct. Relevant issue number SVC-750. Relevant Linden in that issue writeup and its comments.
