Disabled all other mods, except for this modpack in base config and only loading required mods.

Failed to load mods: Error while running setup for entity prototype "maraxsis-regulator-fluidbox-epic" (assembling-machine): fluid_usage_per_tick ends up nan/inf with the defined fluid box filter: 3333.333333 / ((25.000000 (maraxsis-atmosphere max-temperature) - 25.000000 (maraxsis-atmosphere default temperature)) * 1000.000000 * 1.000000)

It named Panglia and Moshine along with Maraxsis as "mods to be disabled" but even disabling those two results in the error. Only enabling Maraxsis however works... So "something" else seems to be interfering. Will try and cycle through the other mods in the coming days, but don't have the time tonight :-( Maybe someone smarter than me has a better idea than trying to manually disable one at a time to find the conflict :-)

EDIT: forgot to mention - without maraxsis the pack works :-)

I'll look into this after work, but binary test (try half the planets enabled with Maraxis, see if it errors, then try the other half with Maraxsis, see if it errors) would help to narrow it down, before testing one-at-a-time with whichever half breaks Maraxsis.

Hmmm, interesting. I was able to find a minimal modlist that causes an error on load, but it's a different one that was reported on the Maraxsis github, as well as on the Shchierbin discussion threads, involving Maraxsis + Shchierbin + Pelagos.

Reverting Shchierbin back to 0.3.1 (from latest 0.3.12) appears to fix both issues, so the problem appears to lie with Shchierbin.
