The issue seems to be when you unload the first lighting scenario you made visible. A workaround is having an empty lighting scenario that is always loaded and visible. You will get this warning: “MULTIPLE LIGHTING SCENARIO LEVELS ENABLED”, but the program does not crash. I’m unsure what this does to performance.
Interestingly, if instead of loading and unloading the levels. You make them always loaded, and just toggle the “Should be Visible” checkbox. One of the levels will remain visible, even when told to be invisible - and the crash does not occur. In this scenario L2 seems to always be the lighting scenario that remains visible no matter if my first key press is ‘1’ or ‘2’. (Adding a scenario that is always visible also fixes this issue here).
