Why does reaper only detect VST3 plugins?

Second post in a row today, so reaper is doing some funky stuff with the plugins and one of them is that It only finds VST3 plugins, I don't know if there is a checkbox somewhere that I missed but I can't find It, reaper overnight started not recognizing the plugins I already loaded in my previous projects.
