This!! Thanks. A broken mod that was since removed - leaves a folder behind and causes havoc. It took an hour but tdeleting the gooe folder solved itMaybe it helps someone: in my case the GOOE mod was the issue. unsubscribe the mod and delete the GOOE folders in
AppData/LocalLow/Colossal Order/Cities Skylines II/Mods
AppData/LocalLow/Colossal Order/Cities Skylines II/ModsData
Then the icons for Move it, Find it etc. will appear (if you use these mods).
