yes, the lag is definitely connected to the Colonist Bar Mod. I thought the features were part of the "patch mod", becaase in my last Game (same download of Rimworld Hardcore SK) the features of the colonist bar mod did not show up. looks like i didnt install the mods correctly at that time, i disabled the col bar mod and the lag is gone now.
Thx for the help!
