I'm playing feed the beast infinity in a single player world. Sadly my setup for automated living wood/rock breaks every time I reboot the world, since the bore-warp burst just goes straight down instead of going from relays to pistons.
The pack used an older version of Botania, but I updated to R1.6-181 to make sure the problem wasn't fixed yet and sadly it wasn't.

Can't reproduce, sorry.

Weird that it's not reproduceable. Maybe it's important that my setup is vertical? Sorry for forgetting to mention it. Here is how it looks: https://i.imgur.com/kj2Y4N6.png

Guess I'll switch to open blocks breakers in the meantime.
