Objects forget their pipe orientation when copy pasted without an active recipe.

This hasn't really been an issue in the past, but now with the ability to set assembler recipes its gotten a bit more annoying, especially with the foundry that only has liquid inputs.

Easy way to reproduce this, make an assembler or a foundry, set it to a recipe that requires liquids and change its
pipe orientation. Remove the recipe (making the input pipes dissapear) and copy paste it, then enable the recipe again, it will have forgoten its orientation.

This isn't an issue in most cases, but if you are setting recipes via circuitry for something like a single-building foundry mall, if there's no active request, the building won't have a recipe, meaning that unless you make a blueprint/copy of the setup while the building is running, it will break when you paste it.

Does it still happen when the machine is connected to a circuit and set to set recipes? I reported the same thing a while back in 118463 and there should've been a fix for this specific case in 2.0.17 (and it seemed to work in my brief testing but I didn't test it thoroughly). It would be nice if it worked consistently, but it should at least work in the situations where you place a blueprint and expect it to work without manually looking at the machine to set its recipe (at which time it's easy to notice if the pipes aren't connected).

Moving to pending due to lack of game version and lack of log file so i cannot decide if it was already fixed or if its a new issue.

I think I may have left factorio running for long that I may have missed the patch this was fixedin.

I think I may have left factorio running for long without closing it that I missed the patch this was fixed in. I just rebooted the game at 2.0.20 and got the last update and builds with circuitry actually remember their orientation now, but ones without it don't.

So the bug was already fixed it seems.
