While trying to start a new game:

Error while running event ccp-noooo::on_init()
Error when running interface function automatic-underground-pipe-connectors.add_undergrounds: automatic-underground-pipe-connectors/control.lua:314: attempt to index local 'pipe_prototype' (a nil value)
stack traceback:

Man, i litteraly have no idea why this happening, i can't replicate error and i aboslutly don't know what's the reason to appear 😭😭😭😭😭😭

Probably a conflict with another mod -I have like 100 more-
I'll let you know if I find the conflicting one.
Thanks!

Here's a hint from the original mod author (I mistakenly posted it there initially), it could help.
