After coming back from an extended break and multiple updates to mods, my liquid trucks have broke and no longer carry liquids or gases; only the cargo trucks work still.

This issue looks to have been brought up a couple years ago? https://mods.factorio.com/mod/Transport_Drones/discussion/6007544581b343c784bcda59

I've been having the same problem since migrating recently and can't for the life of me figure out what's wrong. I know this is an old threat, but could you tell in a little more detail what fixed it for you? I don't really understand what "clearing the lines" means. Thanks in advance.
