so i found this other story progression core mod that i knew nothing about its called simpler90's gameplay core mod before i put this in my game wanted to know does it work with nraas story progression ? cause im not getting rid of nraas story progression nraas im currently running nraas story progression with awsome mod but im willing to drop awesome mod for it

Simler90's core mod is considered unsupported, as noted here: Mod Combinations and Structures We CANNOT Help With - nraas
This means that you can use them together at your own risk- if you encounter any errors while using this combination, we cannot help troubleshoot the issue. It's generally not recommended.

It may help to know that much of what the Simler90 mod does is redundant when using NRaas StoryProgression anyway- because many of the changes are to the EA system that is disabled when the NRaas system is active.
