Blockchain not scanned up to the top!

So, I have compiled Armory from github, using the ffreeze branch.
(My exact revision is 65dafec4ad888219abaa8897929364423f71ea05 )

I could successfully sync up my DB, and I also did two successful transactions.
I know they were successful, because they show up (with plenty of confirmations) on blockchain.info.

But then, after restarting Armory, the transactions don't show up.

Here is the full story:

 - I did a successful transaction, which was immediately confirmed a few times.
 - However, I noticed that armory still showed 0 confirmations.
 - I did another transaction, and Armory said that this transaction might have
   been refused by the network. I want to blockchain.info to check, and
   I saw that the transaction waiting there with 0 confirmations.
   A few blocks have gone by, and it wasn't confirmed, so I suspected that
   maybe I should have set higher fees, and so I wanted to "undo" this
   transactions ... so I told Armory (in the help menu) to
   "Clear All Unconfirmed".
 - Meanwhile, I see that eventually, my transaction _were_ confirmed OK
 - However, after restarting armory, these transactions don't show up at all.
   Neither the first one, nor the second one. Likewise, the displayed
   balance is the one before the transactions. According to armory, it's
   as if those transactions have never happened.
 - Also, the label in the bottom right corner says "Connected (353000 blocks)",
   whereas according to the .bitcoin/debug.log, the current block number is
   371598. Ha Armory forgot to scan the last 20000 blocks?

That is going on here?
