Error while loading item prototype "bioluminescent-loading-ramp" (item): Key "filename" not found in property tree at ROOT.item.bioluminescent-loading-ramp.pictures.layers[0]

I have a decent-sized custom modpack, so I can't tell you what's conflicts with your mod, but I can say that I've got all the three crashes specified earlier in discussion tab.

Which mod are you using which has a "Loading Ramp" in it?

I just encountered a very similar crash: the error message is identical except "bioluminescent-loading-ramp" is replaced by "bioluminescent-service_station" in my case. Perhaps the root cause is the same?

And it looks like the "service_station" item comes from the mod "Constructron-Continued".

I have Constructron installed too, so could be a potential issue

Can you link the mod please?

Found the mod. It's the "Vehicle Wagon 2" (which is loading ramp from)
