That would be super weird. I mean in one pipe, everything flows, one meter down the pipe, everything is frozen. Even the not-so-natural "nothing flows if pipe network too big" feels less unnatural (at least to me). Yes, maybe it is weird. But such behavior could be very roughly explained ...

I understand why the 250x250 tile limit was introduced, but I have a few suggestions: 1. When a pipeline exceeds the limit, make it so that only part that is outside the 250x250 area stops working, but pipeline that is inside continues to work. 2. An indicator of a non-working pipeline. Cool thing. ...
