Bone meal is used up in massive quantities when placing bone meal on the same block as a sign.
To reproduce the bug:
- Place a sign on grass
- Targeting the grass block underneath apply bone meal
- The first use will consume 2 bone meal
- Subsequent uses depending on speed consume anywhere from 4-10 bone meal per click
The bone meal was consumed at a much faster rate than expected (one per use)
What I expected to happen...
Only a single bone meal should be used per use
