Hi @ben I started getting a very strange compilation error in which the hot reload fails in the editor and visual studio wont compile either.

and the compliation log in Unreal:

This all started to happen after I tried (and ultimately failed haha) the challenge of creating the new Turret static mesh component class.
**Even if I get rid of the new class it now wont compile anything. My last commit was a while ago ( Iv’e now learned to love source control). Any help would be apreciated. Thank you!!!

Well, I seemed to have fixed it. The problem was somehow BattleTank.h got moved to the bottom of the #includes list in every single file (I Have no idea how) The compilation really didn’t like this. Moving BattleTank.h to the top of my #includes for every file fixed the problem!!!

Thanks for letting me know you got it fixed :slight_smile:
