Ok, thanks for the info! Guess the zigzag motion could be related to earlier changes then (see Avatar excessive movement, weaving and juking ). I have been experiencing this in some event starts as well to the point of having to look away to avoid nausea.
Glad to see that this part of the product is getting some attention as well for a change. If you haven’t already, you may want to keep the possibility of riding through others still there for the first x meters or seconds of an event to make starts less chaotic/unfair.
