To reproduce:
- Place a stack inserter and set filter to green circuits
- Place another stack inserter and set filter to red circuits
- Place a fast inserter and set filter to red circuits
- Copy the first inserter and super-force-paste (control-shift-click) over both other inserters

What happens:
- The second stack inserter gets its filter changed to green circuits (the copied value)
- The fast inserter is replaced by a stack inserter, but it's filter remains at red circuits (its original value)

What I had expected:
- I had expected both pasted inserters to have a green circuit filter set (i.e. the copied value of the first inserter)

Note that I use the filter in this example, but the same happens with other attributes such as stack size or spoiled priority.

I think overriding the replaced inserter's attributes with the copied value is correct, since I expect super-force-building to copy my original regardless of what is on the position where I place it. I could possibly imagine some reason to keep the attributes of the replaced inserters intact, but then I would expect the same behaviour regardless of whether the replaced inserter types are the same or different.

(I searched the bug report forums and reddit, apologies if this was posted already)
Edit: terminology

There is forced build using shift, super forced using ctrl + shift and paste using ctrl + V.

Apologies if I used the wrong terminology. I meant super forced pasting using control+shift+v

I still think this is a bug: why would super-force pasting an inserter with attributes X not result into the attributes X being preserved if pasted over an existing inserter of different type?

Thanks for the report. There is no such thing as super-forced pasting, so I assume you are talking about super-forced building (Ctrl+Shift+left click). I can't reproduce this issue. You could try posting a video where you reproduce it and your save file.

Thanks for taking the time to look into this.

It turns out the problem only occurs in the editor extensions lab, presumably because it overrides the build functionality. Within the normal world, where actual bots have to go and do the work, the behaviour is as expected. So, it's probably a bug in that mod rather than a game bug. Apologies for not checking this earlier and wasting your time with this -- I could have suspected this would have been detected earlier if it had been in the base game!
