Note for Linux users: If your new PC is running Linux (SteamOS on the SteamDeck, for example - WWE 2k19 runs great on it, by the way), you may have to rename all your game files/folders (including modded and unmodded files) to lower case for mods to work properly (because CCT's Regenerate Chunk0.def feature saves all file/folder names as lower case in the chunk0.def even if they are upper/mixed case which isn't a problem when running Windows, but Linux is sensitive to that - perhaps @TheVisitorX can find the time some time to patch CCT's Regenerate Chunk0.def feature to use the actual case for file and folder names instead so this step won't be necessary in the future).
