Mod bug even after complete reinstallation. Help.

[ballandroll]

The message says it all, but to be more specific, I recently tried to add some personal stuff in vanilla armor expended(Mostly adding one or two new sets) and around with the xml files. it went well until i noticed that the siege armor was bugged and couldn't even find it in the dev window. So, I make a complete clean-up of the mods and the games, meaning I uninstall and delete everything related to rimworld. But strangely, the bug persists and I can't find the siege armor in the dev menu and the armor stat messed up, even after a fresh reinstallation of everything. did this ever happen to anyone?
