I've had this problem lately with workshop mods disappearing from my menu list and reappering when ever they feel like showing up. I tried reinstalling the game multiple times, tried re-subscribing to mods and what not. I just cannot understand for the brain in me why this is happening. And I've run out of ideas and searches to fix this. Apparently it might be related to steam, so has anyone else been through this, has someone found a fix or an explanation as to why mods just don't stay put?
