I just update several mods, including Muluna and now I get this error on startup.

Failed to load mods: Error in assignID: technology with name 'tree-seeding' does not exist. It was removed by planet-muluna.

Planet Muluna

Extraplanetary Production

Ill deal with it later today

+1 but in 1.6.0
When the extraplanetary-production mod is turned off everything works, but with it (latest version) - not. The developer of the mod said to contact you. https://mods.factorio.com/mod/extraplanetary-production/discussion/67fd53d45a0c1daea17bb49d

Nope nope nope I literally cannot fix that its not my issue, his mod loads after mine due to having me as an optional dependency so he's causing the problem

That's what I told him. All right, well, thanks for your time. I'm gonna go talk to Ink_Dash.

You are. Changing the topic of a thread.
Wow.
Very polite.
And its a wellknown issue i cannot fix immediately as im not home. Please check other threads and github before reporting bugs. and dont use other unrelated threads.

Wanted to offer my personal apologies over the confusion on this issue, I've hopefully fixed it by removing an unnecessary reference that was likely causing AoP to load again after it had already fixed the compat issue. I had been under the impression that I couldn't have caused the error but that was clearly incorrect.

Its fine
