Repeter Bug: when you power the repeters with the one in the middle side ways the middle of the middle repeter will turn into a little bit of bed rock

Put the summary of the bug you're having here

What I expected to happen was...:
it was going to act like if you were to normally put repeaters sideways

What actually happened was...:
the middle part of the middle repeater went to bed rock

Steps to Reproduce:
1. Put two repeaters in front of each other (1 block apart)
2. then put a repeater sideways in the middle
3. power a strait repeater
