It is caused by RWTT v2.0 because these waterfalls were marked as deleted in CK, they should have been disabled instead. Most of these waterfalls will be returned to their original place when you visit original location but some will not and there is no way to fix the broken save, until someone make tool that allows you modify saved data. I wrote a small guide on how to fix missing waterfalls caused by broken version of RWTT and it should work for most of the waterfalls. Some might still remain premanently deleted or stuck at 0,0,0 coordinates (exactly where you find them floating above giant camp) and there is no way to fix those, I tried all possible combinations, even moving them manually but they cannot be moved neither via console nor via scripts. Here is the guide anyway, it is worth to try to fix instead of starting a new character: 1. Go to any interior, type in console "PCB", save game, uninstall RWTT mod. 2. Find out the FormID of one of missing waterfalls. If you don't know how to find FormID, easiest way is to remember exact location of missing waterfall, load early save when you did not used this mod and go to that waterfall and click on it while console is open to get FormID displayed on top of console window then type "disable" to check if you selected correct thing. If you did select the waterfall it should now disappear. You can bring it back by typing "enable" but you don't have to do that because we are going to load other save that needs fixing. Write FormID on a paper. 3. Load the save we made in step 1, recruit a follower and go to the place of missing waterfall so it is loaded in memory or teleport will not work. 4. Tell follower to wait there, select follower in console to learn his ID. 5. Enable god mode by typing "tgm" and teleport to missing waterfall by typing "player.moveto FormID" and after the loading screen immediatelly open console again and teleport back to follower by typing "player.moveto FollowerID" and all nearby waterfalls should be restored. --or without a follower-- 3. Load the save we made in step 1 and enable god mode by typing "TGM" in console so you don't die from falling in step 6. 4. Go to the place of missing waterfall so it is loaded in memory or teleport will not work. 5. Teleport to missing waterfall by typing "player.moveto FormID" and you should be teleported somewhere high in the air on the center of the map and you shall see your missing waterfall floating there. 6. When you fall down on the ground use the map to fast travel to the nearest location of where waterfall originally should be and it should be there when you arrive along with all others that were missing in the same zone. Save the game and you should be ok. Repeat from step 2 for any other missing waterfalls you encounter in other zones. What this whole procedure actually does is force deleted waterfall to load and become enabled, it is then moved automatically to original position on zone change.
