"idk" no longer shrugs, instead sanitizing to "I don't know" (#39024)

* idk no longer shrugs

* accidentally had this in here!

* this was accidentally in here too!

* fucked up the removal

* fucked it up again this should HOPEFULLY be the last one

turns out it's hard to revert the edit of a file that's just numbers and spaces who woulda thunk?

* Restore SpaceStation14.sln to master

* Restore development.toml
