Sorry for the problems, UI issue is a rare but known problem and the team is working on that.
In the future and in case that the bug report button is not available (e.g. the game or UI is frozen), if you want to report an issue, please follow the instructions found here http://forum.game-labs.net/index.php?/topic/881-common-technical-problems-and-solutions/, on how to submit a manual report.
