Splitters of all types/speeds take sun damage when regular belts and underground belts don't. Is this intended cause of the 'overheating electronics' thing? It feels weirdly specific and inconsistent to have it affect just them and not the other 2 conveyor types. I get that it's supposed to be similar to Fulgora and Aquilo but the environmental hazards on those planets don't discriminate. If there's no lightning rod nearby, any and every building will get struck on Fulgora. If there's no adjacent heat pipe, any and every building will freeze unless it generates heat on Aquilo.
I'm not a game designer/developer/balancer but maybe you could make it so turbo logistics (and modded ones that use them as ingredients) don't take sun damage? Any player would still be able to rush to Moshine but they'd have to protect their logistics. But if they unlock turbo logistics and use them on Moshine, they wouldn't have to worry about protecting them. It doesnt remove the environmental hazard but does make it a bit more manageable.
Either that or simply enable/disable sun damage for all logistics. For consistency.
