I had these happen for a while now, and so did others on the test server. It didn't happen during release and it may be something related to the language editor, not entirely sure...
Either way, I had them happen when
- I teleported someone to another sector, both us desynched immediately afterwards
- When a player joined.
Don't know what caused 1 to really happen since I can't reproduce it.
Issue 2 might be related to when a player joins and the other one has to download his skin. Either way it's not really reproducible either since when we try it again afterwards, it doesn't happen.
