My head is worth 1000g in Markath due to a museum "job" gone wrong. I was walking nearby when a bounty hunter came and asked if I wanted him to clear my name. I had to pay him 1200g and he would go to the Jarl and set things right. I thought it was a good deal because I didn't have to loose all my stolen stuff and accepted.
After a while I went to Markath and the first guard that sees me arrests me!? I checked the bounty in the stats screen and it says the bounty in The Reach is still 1000.
So is it a glitch or the damned BH fooled me and that's how it's supposed to be?
