I have a bug, where the sprinkler shoots water in more than one direction. I once had it sprinkling in 3 directions. Maybe its a bug with reloading the chunk it is in or something.

I don't really understand what you mean. Maybe screenshot?

Its just like 2 sprinklers woud be at the same place and shoot both water.

Ok, I'm almost certain it's not possible with just OpenBlocks. Probably some tick accelerator or optifine (maybe?). Anyway, not reproducible.

Yes I have Optifine and Fastcraft installed. Sorry that I didnt mention it. And it kinda looks like the optifine update of today just fixed it. Issue can be closed I guess.
