TFWarcry Basically title. I'm playing on a custom modpack with some of my friends, and the host is using Optifine, is that what's causing my mana spreader to not fire into the pool, even though I'm not using Optifine?
williewillus Optifine does have patches that influence game logic iirc, though I can't say if it's causing this specific issue. I'd recommend the CaffeineMC optimization mods instead which try to preserve vanilla behavior as much as possible.
