Current Status (19th April 22:00 CET):
We have fixed the issues. All runs should be up to date.
One exception: There is a bug on gc.com: the very last entry of a TB does not show the mileage. This last entry of each TB is currently not considered by tb-run.com. Groundspeak is already working on providing a hotfix to their site.
In case you still see issues please leave a comment and also mention the concerned TB with its TB ID (TBxxxxx).
