Okay so I'm rather perplexed. I built a waterwheel awhile back and don't remember having an issue. Everytime I've built since I've ended up using the windmill due to what I was building at the time. Now I'm trying to build a mill using the waterwheel but for some reason the millstone will NOT work. I put a foundation down. Place the waterwheel wall followed by the wheel itself. Then I place the junction followed by the vertical shaft. Last I placed the millstone. It all connects and snaps but the millstone will NOT turn and won't let me craft. The waterwheel is IN the water and is indeed turning. I can even look at the driveshafts and they are indeed slowly turning.

So am I doing something wrong or is this broken? I've noticed it's been awhile since this mod was updated so I'm lead to believe it's a bug that hasn't been fixed, but wanted to check.
