I am not sure if anyone else is having this issue but ever since the last update, I am running into constant lag after about a couple in-game days. The lag will continue to get worse until the game is practically frozen. The only workaround I have found so far is just saving and reloading my game. The game then runs fine for a few more in-game days then the same issues will occur. This will happen whether I have 10 or 50 characters on the map. I have tried running on the lowest settings, uninstalled any mods and even reinstalled the game. I am running a 1070 ti and can run pretty much any game I own on high settings so I do not think it is my pc. Any help would be appreciated because I really enjoy this game but this is making it hard to play.
It’s not your graphics card.
The game though is a cpu hog. Multicore really won’t help. (beyond like 3 cores)
What I’m interested in: what’s going on in your map? Did you wall in? Anything else going on? The devs will want a save file 
So… I double checked and I did have a mod from the steam workshop that I was still subscribed to but not active. I got rid of that mod and it seems to be running much better now. Thank you for that quick response though, this is an awesome community!
Which mod was it?
It was the Large Map mod
The one with a huge warning sticker on it warning you that it will slow you down, wreck your home and steal your children :’)? @BrunoSupremo seems the frightnIng sticker still wasn’t frightening enough, add more barbed wire and landmines 
/jk
I removed that warning. For some reason it got into the top mods. I didn’t care about it before and was almost deleting from my hd lol
Because of it reaching a high position, I made that last polish pass on it with new code and the ability to also make small maps, and now I feel it is useful even for me, cause I always loading small maps anyway (through other means)
Anyway, that should not be the cause of this problem, the only time the mod run is when creating a new map. After that, you could even delete the mod and the game would still work with the custom sized map.
It was the topology issue where the AI gets bogged down with pathways I thought it might have been the mod, I have issues with mods in the past. I was just going through troubleshooting steps.
@CplWatkins, @Relyss just reached out to me as well about topology issues and reproducing it. Maybe get ahold of her as well and try to assist with it too.
