Please just warn that mods are out of date, please do not disable gameplay with out of date mods.
Most mods work just fine if they are the wrong version as they do not touch anything updated. There is no reason to force mod creators to go in every single patch and update the version number on their mod. Just give us a warning the mods are out of date, do not pull a Bethesda and make it so every update you put out means that ever mod creator needs to return to the game just to change a version number.
