do you know what I hate? when I join to a game with sim mod on and then I start a game and those mods are somehow still on and this was the problem (= ui lagfix + some other mod caused that your mods stopped work)
so I am sorry for wasting your time problem solved
thats ok no sweat. there definitely was a problem with party - it only happened with a certain setting of 'show tooltips on hover construction info' which is why i didnt get the issue but others did
