Skip ahead broken, fast forward ok?

I have a couple of movies where I can’t skip ahead, and usually I watch from start to finish, so I’m sure there’s a lot more than I’ve noticed. Skipping ahead will make the current time/total time meters break (e.g. current time - (negative) 6hrs).

Normally I would assume the container is broken, but clean remuxes that work fine in other players. Fast forwarding works fine.

Using plexkodiconnect if that might have anything to do with how the video stream is sent to Kodi…

Any ideas on how to troubleshoot?

A good starting place would be to turn on debug logging, reboot twice, reproduce the issue, and then upload full logs and post the url in this thread.
