I just tried it with 1.6.0, there does the issue not happen

Sorry for the inconvinience, it's fixed now with a simple null-check.
I fixed at somepoint the uploading of the backgrounds, must be side effect+ not testing change of background, but only that the upload works...

Thank you very much! The LAN-Party was so stressful that I didn't saw the new commit. I'll test it again and give feedback if anything goes wrong
