thats weird. what other mods are you running

I have had a similar error:
Failed to load mods: molten_plastic/prototypes/compat.lua:1348: attempt to index global 'molten_plastic' (a nil value)
stack traceback:

molten_plastic/data.lua:5: in main chunk

Molten plastic is a dependency for one of the modded planets in the pack we are planning on starting.

These are the only ones being listed of the mod I am running:

biochemical plant (1.0.3)
burner biochamber (1.0.6)
vanilla galore continued (1.4.0)
age of production (1.9.0)
brimestuff updated (2.0.13)
extraplanetary production (1.3.73)

I've narrowed it down to what is causing the issue. All the others listed still work.

extraplanetary production (1.3.73)

its extraplanetary
cant do anything about it the compat is on their side
and for molten plastic powerscooter (the dev) should be working on a fix/already did
