After deleting a c++ class, regenerating solution, and compiling, editor still shows class with yellow question mark?

The only way I’ve found for fixing this problem is to nuke the whole build folder, which means I have to compile everything from scratch, which shouldn’t be necessary for stopping a single class that I deleted from showing up in the editor. Is there any way to force nuke the editor’s cache of that object, or spot recompile the object to specifically mark it as deleted?

?

Yellow question mark is usually the CSM in my memory…
