I noticed, that the interface changed slightly due to some feature updates. Sadly this seems to also have resulted in me losing the contents of a map. I used a JPEG as background and for some reason this was completely gone, even from my upload library. And in the map itself i had set some text markers and those were still there, but some of them in the background, some of them in the foreground. In the past all of them were at the same layer. Thankfully i was able to reupload the file and adjust the text markers. Also only one map was affected. Still somewhat unnerving.
