As the title said, when build by a robot, an inverter is on whitelist mod, making it unable to work unless you modify it's parameter. I'm using KSE but I don't think it change anything.
The problem is not there with a blueprint (since the blueprint save the mod of the inserter) or a copy paste (same reason)

ok this was tricky to fix, and fixing it meant i also had to fix ghosts that previously wouldnt do this as well, but it should be fixed now 👍

Thanks you a lot. Didn't know it will bring you so much pain./ Sorry

it's ok, im glad these issues have been found and fixed, like i said i havent done a lot of playtesting with it yet (havent even completed a full save with the mod yet so that's why i didnt know this robots issue existed yet) :D
