I created a zenDesk Ticket for this on August 4th. Yesterday, September 20th I got an E-Mail that the bug has been solved. So maybe - MAYBE - with the next update this will be an issue of the past.
For Reference, here is the original E-Mail Text:
Thank you for submitting a bug report. Our team will review the information and try to reproduce the issue thanks to the information you provided.
WARNING - Bug reports are not to report technical or account issues that prevent you from installing, downloading or playing the sim. You will not receive further updates or an answer to this ticket.
Bugs and issues that have been successfully reproduced will be categorized and prioritized—game-breaking bugs will receive the highest priority, while middle-of-the-road and cosmetic bugs are prioritized based on reproduction and the number of times reported.
Be aware that the status of your ticket on Zendesk does not necessarily reflect the status of the bug in-game. For more information, visit Zendesk Bug Reporting FAQ or the Bugs & Issues forum.
