Compile error on ANY change

Hi!

Today I tried to make some changes on one of the .cpp files of a plugin I have (it’s on my own folder, not the engine’s) and basically anything I did (even create or delete a comment line) would get me a compile fail with a buuuunch of errors.

I have no idea what is going on, as I had already edited that file to get rid of old/deprecated stuff and nothing weird happened.

Any help is appreciated ^^
