I found a visual bug, basically, if you power a repeater that is facing for example north, and you place another repeater but facing west or east, a bedrock piece appears instead the little torch to modify the ticks.
What I expected to happen was...:
Describe what you thought should happen here
It should appear a normal little torch like other repeaters.
What actually happened was...:
A piece of bedrock appeared instead of the little torch.

Steps to Reproduce:
1. Place a repeater facing north (for example).
2. Then place another repeater facing west or east.
3. Finally power the first repeater and the bedrock piece will appear in the second repeater.

I hope it was helpful, and you fix it.
