Hey there,

Just downloaded your mod today and when trying to place a water wheel, it crashed my game. I tried next with an encased shaft, thinking something stationary might work, but I still received a crash. I'm running Create on my online server, and this is where I tried the function. It didn't crash my server but it crashed my client instead.

Here's the crashlog. I hope you can figure out what made it crash! I really want to build a lovely windmill on my server.

Here's the MC pop-up crash window when I tried again to place a water wheel.

The game crashed whilst rendering block entity
Error: java.lang.ClassCastException: net.minecraft.block.AirBlock cannot be cast to com.simibubi.create.modules.contraptions.base.IRotate

Thank you for the quick reply! I shall give that a try and update with the results.

I am wondering why it won't work in my multiplayer server but it will work in my singleplayer world when I have optifine enabled on my SP game.

I will say, upon testing the same actions on my singleplayer world I didn't experience any crashes. Is this something conflicting with it being an online server perhaps? I hope there's a way to make it work online as I really feel it will enhance the server I'm running to have such a nice mod.

Hi, and thanks for reporting.

It looks like an incompatibility issue with Optifine. I will try my best to fix it soon.
For now, you can disable Optifine or wait until the problem is fixed.
Cheers!~

Okay, so an update: I'm able to run your mod with optifine on my MP server. I had to wipe the mods and do a fresh install of everything on the server and my own client-side as well. Leaving out MrCrayfishs Furniture Mod I think is helping. Without testing to try and replicate that mess, I wonder if there's a conflict between cfm and create. Not sure if it's got anything at all to do with each other, but I figured I'd let you know my progress!
