Put the summary of the bug you're having here
What I expected to happen was...:
Putting 4 entities on a gold weighted pressure plate would produce a redstone signal with a strength of 1, 8 entities would produce a signal strength of 2, 16 entities would produce a signal strength of 3, etc.
What actually happened was...:
The signal strength increased a weird values like 1,5,9,13, and 17.
Steps to Reproduce:
1. Place entities on a gold weighted pressure plate
2. Notice the signal strength increases per every four entities, but at odd values.
