Joining game #105503036 on frankfurt. Later after refresh Joining game #105504659 on frankfurt. Should be the same game though.

Also attached a screenshot in case it's useful.
Edit: Joining game #105504936 on frankfurt with "cotinue with bots" is still broken, I'll leave that as-is for now by closing the tab.
