First mutiplayer tests yield interesting results. I've had reports of strange LOD bugs since SU16 which I simply cannot get to the bottom of. Across two separate flights, every single time my test subjects reloaded the flight something else broke with regard to LODs. Canopy missing, gear missing/transparent, cockpit model not loaded, etc, all seemingly random.
On the bright side, we now have the prop, canopy, drop tanks, pylons, and pilot model* (*2020) synced across multiplayer and all options state saved. It gives us the "appearance" of livery specific options with very little effort by the end user.
