Im playing on 1.12.2 version and no mather what modules/pipes I use, items just go stranding through the whole network and after a really long time they find the way. I don't have buildcraft installed (if it has any affect)

What does "go stranding" mean? And which version of Logistics Pipes are you using (always mention that in an issue)?

First, make sure there is Default Route and that Default Route doesnt full
Second, if you try to do mass-crafting, use other mods instead or atleast speed your machine
