Heatherwood Hall Checkpoint 11
I encountered a bug at this point doing a local co-op game. There are supposed to be two water wheels to lift a gate using water coming in from the ceiling, top-left corner. My game only renders the one water wheel at the right and not the one on the left under the waterfall

The other water wheel is missing, because you are playing multiplayer game. The puzzles are modified in multiplayer to prevent trivial solutions.

So are you suppose to get the water to hit that top right wheel? I'm not playing with Mxyztpik here but I also have this problem with my coop partner. We had it solved 2 different ways and I got the water to hit the wheel. It was almost hitting the top of the wheel. No water was going past us, it was all redirected. We ended up having her load it on singleplayer and beat it so we could get past it. rip.

Yes, the wheel should start turning once the water hits it. Sounds like something bugged out if it wasn't moving at all, but hard to say what could have caused it. Thanks for reporting the issue! I'm glad that you found a way to continue the game.

I have managed to get the water to hit the watermill, but the watermill won't budge. I am playing with unlimited local multiplayer. Please confirm if this is a bug or not.

yep the puzzle is unsolvable, even with perfect flow of water we where unable to do the puzzle in unlimited multiplayer
here is picture of us trying to solve it with double boxes what are we doing wrong?

Sorry to hear you've been encountering this bug. We haven't found a 100% certain fix for it as it seems to occur randomly to some players, but there's a possibility that it's related to low FPS. There are two workarounds that you can try:

1) Return to map and continue the game from the current checkpoint. It'll reload the level and reset the puzzle, which usually helps.

2) Switch to singleplayer and solve the puzzle there (continue playing until you see the "Saving..." message in the top-right corner). Then return to Main Menu, re-host the game and continue in multiplayer as usual. I recommend trying this is the first workaround didn't help.

Let us know if these didn't help either or if anything strange happens.

Yes @AuraFB, your suggested workaround no 2 helps.

That area is actually properly solvable in Multiplayer. Just difficult.

Attach a rope to the wheel with a conjured box. Get the wizard to hold the box up for you to make sure the rope is short enough.

Then have a wizard move the box to the top of the room on the left, so that the wheel turns.

Freeze the wheel with Zoya.

Then attach a rope to a box to the wheel, and walk up the rope. Figure out the rest.

I'm never good at explaining how to do things. I might be willing to help people through ingame if I'm bothered.

My friend and I encountered the exact same bug while playing co-op, one water wheel was missing.

We spent 30 minutes trying to solve this puzzle, I checked a few videos on the internet and noticed a wheel was missing.

This game has been released for ages and these bugs are still out there wasting our time, it's not like it's a brand new bug and it should be fixed by now.

I'm sorry but that's poor dedication from the team not solving this.

I don't think it's a bug. In multiplayer, things are made more difficult, as otherwise most puzzles would be trivial to bypass. Try finding a multiplayer walkthrough, instead of single-player one, if you still need help.

I think it's a bug, I watched some walkthough but we end up having a missing wheel and no lever on the top left corner.
