Mod version: 5036
I am on a server

I was building a turbine room, and when I decided to shut down turbine 2 the ducts kinda just shit themselves and both of them shut down. I have replicated this bug every time, closing and opening valve 1 fixes it. I took a video to better show what I mean:

Just found out, the valve that stayed open acts as if it is still closed if the other valve is opened. I dont expect this bug to do much other than break automation if it affects redstone valves too, though.

interestingly enough i tried to replicate your bug, it did actually fix itself. Maybe its because you're on an older version.

I can't replicate this either, it might have something to do with the issue where valves would disconnect which itself had a more severe underlying issue, but that was fixed a while ago. It looks like you're on an older version because the boxducts have some minor graphical jank that was fixed this week.

The barrel might be changing things. In my facility, the barrel is just an infinite water barrel that goes to 4 geo exchangers. That might cause some differences? I'd test in a newer version but I need the server owner to change it, and he usually waits a while incase bugs occur.

Can't reproduce, still on the old version. It's probably the server.
