Engine v5.0.15

A patch to For Real.

• Multiple moving shadow-casting lights now all keep their shadows — previously only one moving light at a time could.
• Fixed long lag-behind sessions endlessly rubber-banding — the game now does one clean catch-up resync instead.
• Fixed buttons and controls permanently dying after a slow game load — presses no longer "work for a split second, then snap back". If your game's UI broke when you updated past 5.0.7, this is that fix.
• Lights are now easy to select in god mode — the click target is the light itself, not its entire glow radius.
• Fixed a rare condition where the game stopped responding to your controls after a server restart until you reloaded.
• Fixed a bug where a world's ground and collision could fail to load (players falling or floating at spawn) when an asset server was slow — terrain now builds reliably even when assets are having a bad day.
• Worlds with freshly generated models load more reliably — slow first-time asset processing no longer makes physics and models fail to show up until a retry.
• Ground textures in 2D games no longer shimmer while the camera moves.
• If your world ever stops drawing, the engine now notices within seconds and tells Savi exactly what happened — that it's a graphics-driver problem a browser restart fixes, not a bug in your game — instead of leaving a silent black screen.
