Please also include the save file(s), any mods you may be using, and any steps you know of to reproduce the crash.

What did you expect to happen instead? It might be obvious to you, but do it anyway!
Game would show Mod Error instead of Crashing.

Does it happen always, once, or sometimes?
- Scenario crashes immediately when Played as a New Game or when loading Autosave
- Scenario crashes when switching to a Platform
- Does not crash in Scenario Editor if you stay on Nauvis, even while "Ticking"

The stack log from the crash seems to indicate that it is in the DrawEngine/GameRenderer; disabling the mod FPS Friendly Thrusters stops the Crash from occurring.

Ok i can reproduce the crash, but that requires having `FPS_Friendly_Thrusters` mod installed. Scenario itself it not relevant, its just having a thruster visible on screen.

The point of the scenario is that the crash does not occur if you stay on Nauvis while the game is running.
When loading a savegame with a Thruster it crashes instantly.

This behavior difference suggests to me that the Thruster graphic is being rendered when loading the game normally even though there are no Thrusters on-screen anywhere - ie, this is a possible Performance Optimization.

You are correct, by not defining the plume effect and the subsequent bounding box in it, it will always be rendered. When they are defined the bounding box will stop it from rendering when that area is not on screen.

Essentially, remove the mod and it will fix the crash and still have identical performance.

Also, the crash is fixed for the next release.
