Hiya! FYI I think you've created a loop in the streams. You can see loops here: <https://waterwaymap.org/loops#map=14.84/53.93014/-7.15049>. In this changeset, you added a few `waterway=stream` and that made a loop. I think it's the northern half of the loop in that link.

I'm not sure what to do.  Are you sure all the directions of the ways is correct? Maybe we can figure out if some/one is pointing the wrong way. Are these things `=stream`'s or `=ditch`'s 🤔
