When you are on the hopper and dropper interface, you try to move a stack and it won't let you.

I am using a Samsung Galaxy Grand Prime. I made a YouTube video on this glitch.

When you transfer stackabe items to a dropper, hopper, Dispenser, or vice versa, the animation moves where your finger moves. You can still transfer items, but sometimes it get glitchy. Please fix by the first 0.15.0 build, since you changed the name to "Realms alpha build"
