So my question is about that I downloaded the cheat room mod because I got stuck in some cave because the bloodskal blade would not shoot its beam and I went to the room drank a health potion and now I un-download it, because its not fun with cheats, but now my health won't take damage, what do I do? I un-downloaded it and I'm on XboxOne and I do not want to go back to an old save. I got rid of other cheat items but my health won't go down when attacked.
You need to load from a save prior to when you had the cheat installed.
Console mods for Skyrim and Fallout 4 are often somewhat hacky, as they lack the options and script extension options that exist for PC. Many mod authors who do console mods also are relatively new modders compared to those who place content on the Nexus, as many of the more seasoned modders refuse to participate in Bethesda's console mods.
What has probably happened is that the "mod" simply set your maximum health to a ridiculous amount, set your native damage resistance so high that you can't be effectively injured, or bypassed the lack of console commands by effectively setting "TGM" (godmode) to true and had no method of turning it off.
In any of those scenarios, all saves made after the mod was active will be permanently affected by the mod. This really only leaves you with one choice.
