Since 22.01.26, Mod is incompatible with Muluna.

Error message describes a problem with prototype next_upgrade muluna-cycling-steam-turbine (fusion-generator) to the fusion-generator-mk2.

Bounding Box seems to be different.

I'd highly appreciate it if this could be fixed :)

Thanks

same with https://mods.factorio.com/mod/lilys-cubeine:

Error while running setup for entity prototype "cubeine-fusion-generator-cold" (fusion-generator): When next_upgrade is set entity mining result must not contain item product with "hidden" flag set. Mining results with no item products are allowed.

problem's probably in prototypes/entity/fusion_reactor_mk2.lua, the new lines

data.raw["fusion-generator"]["fusion-generator"].next_upgrade = "fusion-generator-mk2"
data.raw["fusion-reactor"]["fusion-reactor"].next_upgrade = "fusion-reactor-mk2"

Muluna and Lily's derive from that, so if you change the prototype, they inherit that, too, and aren't prepared for it.

If I delete these two lines from prototypes/entity/fusion_reactor_mk2.lua and move them to data-final-fixes.lua, Factorio starts without error. I have no idea though what that change possibly breaks.

Please think about providing a fix, I think the possibility to make them upgradable via next_upgrade is not worth it when it can break other mods...

Thank you!

I'll take a look tomorrow to see what the problem is exactly. But I suspect that the other mods are somehow trying to make the fusion reactor upgradeable.

hm, looks like you're trying to make the base fusion reactor upgradeable, the others inherit, thus break? Thanks for your time!

Reverting this mod back to 1.1.4 fixes it to load for now

It should now work with both mods :)

If you notice another mod that causes this problem, please let me know. It should only take a few minutes to fix.
