* * Ensured `TSPlayer.PlayerData` is non-null whilst syncing loadouts. (@drunderscore)
* * Detected invalid installations, by checking for a file named `TerrariaServer.exe`. (@drunderscore)
* This made the two most common installation mistakes (extracting into the Terraria client directory, and extracting TShock 5 or newer into a TShock 4 or older install) prompt the user with a more useful diagnostic, rather than (likely) crashing moments later.
* Changed Bouncer to block updates which set the following fields to infinity or NaN: player position, projectile position, projectile velocity, item position, and item velocity. (@Arthri)
* Updated `TShockAPI.Handlers.SendTileRectHandler` (@LaoSparrow):
* Fixed incorrect validating range in `TileRectMatch.MatchRemoval`.
* Fixed tile rect changes (e.g. turning on and off campfires) are not synced between clients.
