Hey, I just got this error while loading my game with your mod:

Error while running setup for entity prototype "hephaestus-processor" (assembling-machine: next_upgrade target (assembling-machine-4) must have the same bounding box.

The other affected mods are:
planetaris-dyes, module-category-defaults, Bottlenecklite, Construction_Dones_Forked, maraxsis, panglia_planet, plasma_crafter and foliax.

Thanks for your work <3

Worked some crazy long shifts recently, going to see if I can look into this tonight

Thank you for the report

Looks like I can set next_upgrade = nil and hopefully prevent that error.
I was not able to replicate this error, so I don't know which of the mods conflicted, but this change should prevent conflicts with other mods that allow for assembler 4+ style entities.

Putting out update shortly.
Please let me know if the error persists.

Thank you for the patch, unfortunately you forgot at least one other entity "hephaestus-requisitioner", which now spits out the same error, because I'm guessing it also can be upgraded to 4+.

But we're getting somewhere! :-)

d'oh

Okay, just put out an update, put next upgrade nil on all prototypes that are based of generic assemblers,
hope this helps!

This helped indeed! I am once again able to load up Hephaestus along with all the other mods, thank you.

I cannot say anything about the actual functionality, as I've not yet landed there, but I'm sure it's all fine.
