Along with a lot of mods on Minecraft 1.7.10, version 1.8.9 crashes when I try to fill a wodden cup with water.
With version 1.8.8 I can do it without problems.
EDIT: Now it's working, but don't understand why. I've tried 1.8.8 then go back to 1.8.9 and I can fill my wodden cup.
On Dropbox, the last version for 1.7.10 is 1.8.9. But PitchBright here is right, 1.8.14 is also for Minecraft 1.7.10.
Update: I've found one more problem. I can't get the recipient full from the rain collector. It dissapears and appears again in the filling slot.
