... know that they should be rotated, and they break.

This bug affects all assembling machine prototypes (when rotatable), Pumps, Fluid tanks and Asteroid collectors.

Furthermore, the original bug still occurs on Loaders, Valves, Lane splitters and burner generators.

A fix would be greatly appreciated.

... this same fix.

Mods are required to use Loaders to begin with? The ones available in Vanilla Editor Mode have very obvious "Developer Graphics", just like the other Creative tools (Infinity Chest, Heat Interface, Valves). Depending upon these items in a share-able Blueprint seems like a Bad Idea.

As in title. Allow entities of the valve prototype to have circuit network connections, particularly for "Read contents". This would allow valves to do everything that the psuedo-valve tanks of 1.1 could do.

Why it's in "Mods" section? Valves are vanilla functionality, available in editor.

Yeah, the bug has something to do with the removal of the internal valve entities - whether that be by migration from valves 1.2 -> 2.0, or removing the mod entirely.

It's not the mod's fault, it is simply triggered by the mod's behavior.

Weird. The valves in the save are old ones (version <= 1.2.1). But the issue happens even when loading the save without any mods at all. Of course in that case everything is broken, but those pipes shouldn't look like that as they're not even the ones adjacent to removed entities

This appears to be related to the Valves 2.0 mod - if I keep valves on 1.2.1 then the issue does not occur.

If you want to play with the new valve prototypes then check out the Valves mod ! It now uses the new prototypes provided by the game engine. Additionally it allows you to easily configure the threshold in-game for every valve you place (based on some default settings), whereas the vanilla valves has ...

... casting recipe active and you want to change away from that recipe: it will not change until the input fluid is empty, which needs one more set of valves/pumps. Because of these kind of edge cases, I gave up that general design.
