Hi :)
Freezing prizes as a mechanic has been removed for this run of Gone Yak Tracking as we are trying out a load of different mechanics when we rerun these! I'll take a look into the other issues you have observed.
Edit: I've had a look at the issue with it costing 150 oddments. It looks like the text is incorrect here. The actual price for refreshing will be free. Will get a job in to change the text. Thanks for raising this!
