Hi Adum, another one that failed.
I tried to add a missing solution to problem http://goproblems.com/prob.php3?id=17820 but it does not show the changes, while in the problem history the new version shows up just fine.
Maybe it is the version number? Like the problem chooses the most recent version by version number alphabetically, so version '9' is prevalent above '10' ? IDK...
Thanks, Bart
