Without looking, it’s likely the same issue as with all of the various wall lights: there’s no good vanilla way to make a light source come from a different cell than the building. Every time someone makes a new wall light mod, they create a new custom offset glower, which unfortunately tends to require specific C# patches to support.

I tried to make handling that generic, so it typically does manage to locate and patch custom glowers, but there must be something about this one that makes it harder to detect.

Patching the KeepOnComp onto something will unfortunately never work, as my mod removes it from any building it can’t find a supported glower on to avoid cases where the comp shows even when the mod doesn’t work. That also helps troubleshoot things like this, where I can be certain that it’s not being detected as a light.

I don’t know when I will have time to look into this :(

I really appreciate your response.

You're correct in that Gloomy has it's own custom glower and Gloomylynx.dll handles it. W/r/t KeepOnComp, that makes sense; I respect your codes elegance.

This isn't a game-breaking problem and I understand we all have real lives. If you ever get around to adding GL_Wall_Lamp's to your script then one day I'll load up my colony and get a pleasant surprise. Cheers.

You could always add support if you’d like, the mod is open source and I am more than happy to review pull requests. I imagine it would essentially be the same as the Murmur and VE wall light patches I already have, just for that specific scenario

I had the same thought after my post yesterday; I was doubtful I'd be able to contribute, but since you've pointed me towards your VE code, I gave it a shot. I am not a talented C coder, and this might be a terrible idea!
