Can't select a difficulty when I have your mod installed. I do have quiet a list of other mods so not sure where the conflict lies.

Thanks @Mangles
Can you share the list of mods?

I made a collection of it recently: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3078264382

Having encountered the same issue, it was one of BFX [Utility] or Expanded Challenges [Utility] that seemed to be the problem (turning them off seemed to fix it).

Hi @Null_Error thanks for the details. I take a look at this two.

Running through identifying what mods are conflicting I found that these two mods conflict with your mod:
Tianjing-ViolenceAesthetics
原版信号补充-Original Signal Supplement

These mods did work together:
Mod Options - v0.4.1
KANA BFX [Utility]
Pototos
More Elites + Boss Rush Mode
SCGM-AuxiliaryExpansion
Diversified v0.5.0
Pack] Witchery
Eientei
Expanded Challenges [Utility]
Sound Fixes
Wider Character Select
Start Items-1.3.3
Item Selling
Extatonion Mod
Pack] Mashtato
Brotils [Utility]
ContentLoader [Utility]
No Achievements Version] Genetically Modified Overkill


One note is that disabling them using Mod Options didnt avoid the issue, instead I needed to completely uninstall them to get past the error. Hope this is helpful!

@Icthulu thank you very much that helps

Isnt working, i downloaded the 2 other mods needed to run this, tried uninstalling other mods, still not working

Nvm i re-installed it and now it works
