Not only their visual is broken but they also don't work as real undeground pipes.

Is that supposed to be so?

Oh the f... Press G to do something in is the settings and not the first pipe itself :D

you got it! lol

Is there an option to get back old undeground pipes? New ones feels awkward to use, specially with alt mode showing each undeground tile everywhere and graphics are not matching the plain pipe >...<

Also new ungeground pipes are blocking all interactions with places tiles above them. Like I can place pipes below chest but I can't use chest after that.

This was all fixed previously. I haven't done 2.1 migrations yet so maybe it bumped you down to an older version of the mod? I'm updating everything for 2.1 over the weekend

I reverted factorio to 2.0 to continue playing (at least trying to play) on this version. Its more about usability of the new undeground pipes system. It is really good to have option to place undeground pipes as player wants to, but they block everything above them so play can't interract with that stuff and alt-mode shows their content images, which makes even small base look bloated with them.

(and yeah, old issues fixed, thanks, now it shows that I can place the undeground pipes right after placing first one and also ability to click-click 2 locations to place undeground pipes)

ok. I'll take a look at it. I'm going to push 2.1 updates to the whole collection over the coming days. The fix will be included
