Beware, I use lot's of mods so it probably comes down to some mod compatability thing.

I get this error on factorio 2.0.23 with mod 2.0.1, got an idea on what that could be?

4. https://prnt.sc/hgQKJ4f10XFP

And after "Waterfill", only 1 mod follows: "Wood Gasification updated"

When looking at the mods and thinking about potential collisions, I can not think of any anymore, you probably are smarter than me.

Will check this out in the morning. Can you tell me what settings you are using? I suspect something broke while updating to 2.0/I forgot to account for something. Doesn’t seem to be a mod incompatibility from initial guesses

Mod settings of your mod? Default. It is the first time installing the mod :D

Oh interesting. My initial assumption was that you were using some special settings for a module which caused the crashes. In this case it is likely a mod incompatibility? Does it crash when this is the only mod you use?

I'll see, but I assume it will just work out of the box, need to save my modlist n stuff.

So,

5. https://prnt.sc/VLp19DyxnGyM

With this mod collection, it "crashes" on startup, but as soon I disable "Phidias Collection" it starts just fine.

Hey, is it possible you were trying to change an effect on a module which doesn't normally support it by using a basic setting? For example, giving productivity on a speed module a linear pattern.

If that would be the case, It would have not been me doing that in the mod settings.

Could another mod be the culprit of that? I have no idea :D
