Nothing amiss (I'm guessing), just some way splitting involved.

Way 26468813 may look like a new way, but I'd guess it was actually  
formed when an older way was split. That'll be where the  
"history=Retrieved from v4" tag in the first revision comes from.

It would be good to agree a tagging system for when a way is split/ 
joined, to provide some way to reconstruct history in cases like this.


As a side-issue, I'm guessing user BeKri used the revert function  
here to abandon _unsaved_ changes. Nothing really wrong with that,  
but Potlatch should probably be smart enough not to write a new  
revision in such cases, even though that's ostensibly what the user  
has asked for. I'll fix that in a future version.
