I had one tolken, that the game wasn't letting me spend, and now it has disappeared
It went on a bid at 2016-12-19 17:18:51 GMT. You also spent one 5 seconds earlier on another bid. These two bids were on different staff.
The first was on:
https://igpmanager.com/app/d=staff&tab=contract&id=128523
The second bid (which spent your last token) was on:
https://igpmanager.com/app/d=staff&tab=contract&id=143189
As I can see, you also won the auction you spent your last token on since that staff is now in your team.
