The "Latest tags" value seems to be cached for the changeset number.
Created originally on Bitbucket by DeeHants (Deanna Earley)
I have some incorrect values being shown for the "Latest tags" value: This occurred after I had created the build on top of 2146, then tagged it (in 2147 and 2148). These were both stripped, 2 more changes made, then the same procedure done again on top. (All build changes and tags were done outside thg, then thg was refreshed) If I close and reopen the repository then the latest tags shows the expected values.
