Hey, I made the mistake of renaming the prefab perks and wallbuys etc to something a bit more userfriendly, and now since the update that came out that fixed gobblegums, my machine isn't working? What do?

I think the easyest way to possibly fix this is to, go into your Steam>Tools>BO3 MOD TOOLS>Properties>Local files>Verify files integrity, then, probably Steam will download some files and your prefabs will be fixed, hope I helped      sorry for my trash english.   
OBS: If you search in Google "How to verify files integrity Steam" you will find a tutorial in Steam support teaching you how to do this better than I teached and with a better english
