Hi,

creating a new world with multiworld leads to a world without mods (e.g. plantmegapack and missing things from other mods like missing trees from pams harvestcraft -crops are there-).
Well im using 130 mods and im sure there are some more missing mods in my generated multiwold.
Is there a solution to generate a multiworld with all the same stuff(mods) from my mainworld?

Im using version 1.7.10

Thanks for your fast answer.
I created a new normal world. Just using /mw create nameofworld. If im listing the worlds, they are listed as normal.

If you create a normal multiworld, it should look the same as the default one, including all modded content. Maybe you didn't select the correct world provider.

Some mods are hard coded to generate blocks only in dimension 0 aka Overworld.

As we moved to 1.12.2, is this still an issue? Closing this issue in 7 days if no response @Poketechserver

Actually, closing this as we cant fix this on our side. Refer this issue to any mod that prevents generating blocks in a Multiworld overworld.
