I have been keeping an eye on the options and suspect a couple of buyers may have been caught out/confused.
The 13 October 2014 options with exercise price $0.30 are quoted as TRFOA
The 20 May 2015 options with exercise price $0.20 are quoted as TRFO

There are curently bids for TRFOA of $0.021 and 0.020 whereas there are TRFO options (10 cent lower exercise price plus 18 months more time) for sale at $0.028

Hope this is helpful...
