DLC and mods

Hi I have been playing the game with various country mods installed like the Netherlands , Sweden etc. I then bought the 2 DLC packs and had game crashes. I then reinstalled the game minus mods with dlc and all is ok. my question is - can I now use mods again or will this cause crashes. I’ve seen youtube vids of squill playing the extremes dlc with republic of Yorkshire (hilarious) mod so wonder if I can use country mods again. thanks in advance.
