Cover installation, it doesn't matter. Generally, MODS doesn't seem to change the game file. They are all newly built. If you feel uneasy, reinstall MODS like OOO. Do not reinstall the clothing MODS. Don't tell me you didn't back up MODS. In fact, if you are ready to back up, it only takes a few minutes to reinstall the game. I just put the data on the mobile hard drive. If there is an error, cover the installation will directly overwrite the data.
