[Talk-gb-westmidlands] River Tame relation broken

[Andy Mabbett]

Our relation:

    https://www.openstreetmap.org/relation/7928300/

shows the Tame rising near Halesowen (it actually has its source at Oldbury ).

Judging from the history, it doesn't seem to be a recent phenomenon,
and I assume someone acting in good faith has added one of its
tributaries

Viewing it in JOSM, I'm not sure how to determine which ways should be
removed/ moved to a different relation.

Please can someone fix it, or better still show me how to?

I think it would be easier if there was a graphical representation of
the relation, and I could just click on ways to add or remove them. Do
we have a tool that does that?
