Idle master "doesn't loop"

[VanackSabbadium]

Hi.
First of all, thanks for this project, it's amazing to have a *nix port of Idle Master.
However, at first it worked without any issue... Now this happens: i launch Idle Master, it starts dropping cards, and when a game has finished dropping, it doesn't move to the next game, it stops to "Sleeping for 5 minutes", and it repeats it forever.
The thing is, if i'm at the computer i can stop the program and launch it again, but if i want to launch it and go to bed, next morning it only dropped cards for one single game.

What can i do?
Thanks in advance!
