Title. Am playing on K2SO with a couple planet mods if that's relevant, but I noticed that when making Electric Engine Units, which require lubricant, the Assembling machines spawn incorrectly rotated such that the fluid input does not touch the pipes. After manually rotating each assembly machine, the blueprint works correctly

Which assembling machine from which planet mod? I'm testing few ones including the assembling machines from K2SO I cannot reproduce it:

Huh, that's weird. Just plain Assembling Machines Mk3 in my case. The recipe is being spawned like this for me:

Send me a screenshot of the GUI of the machine so I can check what mods are doing on that machine: https://imgur.com/a/64cUrnY

Fixed it at v1.2.4,
The problem was Muluna who changes the type of the fluid port, should be ok now.

Nice, thank you for the fix!
