I've had some issues with Iron Pipes regularly (sometimes) change their clear direction after world relog/startup.

@RagaRBM - any way to reproduce?

@asiekierka i've run intro this a while back myself if i rember correctly it heapened afther a relog with iron pipes connected to stripe pipes (stripe pipe had a gate and pipe wire was running on both pipes, not sure if that matters though)

Did the gate have a redstone action configured? Perhaps before everything load when logging in the world the gate action activates and it emits a redstone signal.

i don't think so, it's been a while since i last run intro this, i didn't build to much of these kind of contraptions recently

Irreproducible, apparently. Closed until it becomes reproducible.
