This edit has gone a little wrong and has lost important information.

Have you visited and seen something that has recently changed?

In merging 'identical' ways together you have also merged the way that connected them which is not identical, https://www.openstreetmap.org/way/925258534/history. This short section is in a culvet so no boats can pass, unless of course its a coracle which you can carry.

This edit needs to be reverted however I am intrigued as to why you made it.
