Sounds like it's somekind of glitch in the game, so I guess only @Fredrik-Unibet (or @Ray-Unibet and @Jeppe-Unibet) can forward it for the developers to be checked. When they come back to work in the morning ofc. Give it some time and they'll see this pretty soon
Also before their working time begins, it may speed things up if you can tell the exact time when it happened, (spins can be seen in the casino history at main site's profile) and as detailed information about what happened is always helpful too.
I think it happend around 23:57 central europe time
Thank you @Fetteranton, I'm having one of your local Customer Service agents try to find the round and have it checked - they'll get in touch through email.
