When I shear sheep by pressing the shear button, the action works, but the sheep are injured.
By the way, my title screen says "v0.12.1 alpha" despite that version not being available in the drop down field in this bug report.

Moving to MCPE-10490 due to more overall ticket.
We are aware of the 0.12.1 not being available. That will be fixed for tomorrow.
