Videos are "downloaded" but not "Available right now" while being available

[Raptor05]

I had to restart my server today (Synology NAS) and therefore also restarted the XBVR container. While it started, the external drive with the video files was not available yet. I've restarted XBVR later manually, since the UI was not reachable (didn't check the logs).

After the restart, only ~190 of 900 videos where "Available right now", the rest was only "downloaded". This makes no sence, since all videos are stored on the same device. After another restart, the file number changed to 23.

Then I've renamed the folder mapping in the container config (since I'm not able to change the physical path, since it's a generated path by Synology for making external drives available. I've started another scan run, then renamed the folder back to the correct name, started another scan. Now, 91 files are available, but still 870 files are only "downloaded". I still can start the video from XBVR UI in the preview player, so there are definitly available and online. But XBVR denies to show them so. The issue is, that these videos are not shown in Hereshpere, as long as they are not "available".

Any hints on how to solve that issue?
