As the title says, tested on ubuntu 18.04 and opensuse tumbleweed. Both VM.

Example:

I have some transfers completed. I delete them all and then shutdown the system either via graphical interface or via terminal. Next time the vm starts the transfers will be back but red with error "edge file missing".

It causes no real trouble apart from having to re-remove the transfers which is more of a nuisance. I've got used to first exiting tixati manually then shutting down/restarting, but sometime I forget.
