I am running a bob's angels which might be the issue.

There is no crash in game, however each time I send a fluid down to the pipe-layer the fluid fills the pipe on the surface but does not "enter" the pipe-layer (I cannot see the icon of the fluid on the pipe-layer).

After which putting a back to overland pipe appears to not connect no matter how many times I flip the input - output setting.

Might be my mod list or stupidity but it was working as far as I could tell back in the 18.27 ish days.

Same problem here

I’ll need to have a look. Something maybe have been affected with the recent fluid system changes.

This should be fixed in v0.4.3.

Thanks a lot got to game yesterday and everything is connecting again.

Cool mod saves me from gouging my eyes out at the sheer weight of pipe work needed in bobs & angels.

I downloaded the lastes version (as for today 0.4.4) and still has the same problem

Not sure if the print-screens help
