Found somewhat of a fix for what people might be experiencing, or at least a start.
First get "Fishery - Modding Library" and it's other dependency from RimWorld > Workshop.

Load the list and then remove everything after "XVI-MECHFRAME".

If will take a bit to load, while looking like it's stuck, but it will work.

You can add "RocketMan - Performance Mod" and it will still load.

What is left is to manually try and add the last remaining 10 mods one by one to see which one ♥♥♥♥♥ it all up.

I'm also stuck on initializing, any advice would be appreciated.

I'm getting the same issue as dhowr101

Can not get past the initializing phase of game startup. Used the rimpy and have a solid computer. Any tips would be appreciated !

Another thing that I note too, after add this series mods like warhammer and grimworld the RAM used up to 25GB but after some time the game it's self run something like GB system and free the memory. The first test without adeptus series low to 4-5gb. Now that I found this issues mention early I don't know how much memory will be free. Take some minutes 5~10 to free all I belive.

I note that apparently have some issue in mod orders, initial I thinks was Adeptus series because that showed in log errors, but after some tests I note if I remove industrial mods it loads normally. If you try run the game with this logs that show only once after game starts you will have issues during gameplay.

This lags it's because of that, some units could just stop move and for "no reason" the FSP drops to 20 capped or even low. That could be too because other "essencial mods" that I use, for now I will try play without the Industrial.

I already make it works withou adeptus series mods too. Maybe it's not the same issue of others, but could be something like it.

@spvp313 If everything is exactly in the same order then it might be an issue with your pc. or other mod configurations. 4 tps is really low. might be a mod doing it so go into developer mode and look at the logs to see the errors

Sorry i have a question im new to modding and im stuck on 4 tps and i dont know how fo fix it ive installed the same stuff as you and i have rimpy but it still is at 4tps

@dj_jo_killer_dk yes from "replace stuff" mod. I would recommend normal coolers instead of over wall coolers

im using rimpy for load order, but i think im missing coolers ? i got the over a wall cooler but cant use it because pawns dismantle the wall under it when constructing it.

@vreek_freek you can use Rimpy to import the same mod order. or you have to do it manually ingame. I would recommend Rimpy

im having trouble putting these mods in order. can someone help me out with it?

-Thanks in advance.
