Factorio Forums

I noticed when I pasted down a blueprint with legendary roboports and bulk inserters, they were actually created even though I didn't have any in my network (haven't even researched legendary yet).

This is Version 2.0.72 (Build 84292, expansion, win64).

Can you please provide a save file and or video showing what you're referring to?

EDIT: Further research shows this is likely caused by the "Nanobots: Early Bots 2.0" mod. Issue was reported here:
https://mods.factorio.com/mod/Nanobots2 ... 7b13b9af32

I've been able to replicate this by placing a blueprint with higher than normal quality and having the item of normal quality in my inventory, then the nanobot places the legendary instead of the normal.

This mod hasn't been updated in a while, so I don't think this is a Factorio bug. I'll leave my original reply in case it's needed.
END EDIT

I've experienced this as well with long handed inserters.

I placed a blueprint from a previous game and came back later to find legendary items had been placed. This is correct with the blueprint but I haven't left Nauvis, so there's no way I could have researched it yet.

Using around 15 mods, same version as original report [2.0.72 (build 84292 expansion, win64)]. I will include the closest saves I have to before and after I noticed this. Let me know if I can provide anything else.

Ah, then yes that’s a mod issue.
