Have to disable Larger Lamps with the latest Freight Forwarding update or the game will not load.

It works fine for me - are you able to share the error message please? Or the list of mods?

Failed to load mods: Error while running setup for entity protype "deadlock-copper-lamp" (assembling-machine): next_upgrade target (deadlock-large-lamp) must have the same fast_replaceable_group (lamps != large-lamp).

Then a list of mods to be disabled
DeadlocLargerLamp (1.5.0)
FreightForwarding (1.5.0)
extended-descriptions(1.1.0)
Hovercrafts (1.2.2)

Pastebin of last log, might have more details but looks like the same error message.

Thanks - I haven’t tried it out myself, but I think the problem is between Larger Lamps and Afraid of the Dark, I don’t think it has anything to do with FF.

That is most likely it then, thanks for taking a look!

I have confirmed disabling afraid of the dark allows larger lamps to load without issue.
