This seems to happen with any extra.
I have PMS installed on Windows 10, with Plex on a separate Mac that is hooked to the TV.
I have local media movie extras, named accordingly to (https://support.plex.tv/hc/en-us/articles/200220677).
But everytime I play an extra, for any movie, it will play, but once I fast forward, or go to stop the playback, PMS promptly crashes, every, single, time. I can play the actual movie, fast foward, etc just fine. TV Show, just fine. But when it comes to extras for movies, it crashes. I do not know about TV Show extras, as I do not have any.
I have a crash report in the Plex folder. I have attached a couple server logs (Plex Media Server.log). I can attach the crash log if requested.
I am not sure what the issue is.
This is on server version 0.9.16.6
edit 1: Updating to latest version (1.1.3.2700)
edit 2: Seems to be fixed with update to the newest version.
