TeamX Patch 1.2 converts my version to the american version? Oh and how can I find my save files so i can back them up?
No, backups won't help. Installing the patches makes the files unloadable. You can keep your current game, OR you can install some mods, but you can't have both.
Many games suffer from this kind of dilemma, sadly.
The gog version is censored?
Yes, the UK version came out after the US version and had some updates to it, so GOG based their version on that, but it also had many things censored to be UK acceptable because they're stuffy like that.
