"Generate" button for world creation not working with other mods

[skellitor301]

O.S: Windows 10 10.0.19042 Build 19042 64Bit

RimWorld: 1.3.3071

Problem:
Likely a mod incompatibility but I'm not sure which. The conflict prevents the Generate button on the Create World window to work, and the error " Exception filling window for RimWorld.Page_CreateWorldParams: System.NullReferenceException: Object reference not set to an instance of an object" pops up. Expanding the error provides the following:

Thanks a lot for your report! 👍

This was probably a conflict with a mod, but it's hard to say for sure (although I really do think it was). This should be closed with 10c3045.

Already uploaded to steam workshop. From now on there should not be any conflicts left with other mods as I removed all possible source of conflicts.

While I don't think it's possible to have this mode conflict with another mod with the new changes, if you ever stumble upon the same problem, feel free to reopen this issue!
