Edit: "Rebuild and Rescan Databases" from the Help menu fixed it.
Windows 8.1 x64
I have bitcoin core 0.10 installed and Armory 0.93.0.82 running. I sent a transaction to my Armory wallet from a web wallet. Originally it showed as having received the transaction and 0 confirmations but it never went above 0 confirmations even though online block explorers showed it as having been confirmed many times. Then I realized that Armory shows "connected" in the bottom right but the block count isn't increasing. It is still stuck on block 347509 while current block count shows 347813. But Armory shows as connected and Green.
I ran bitcoin-qt and it showed the correct number of blocks.
I tried "Rescan Databases" from the Help menu but that doesn't seem to have fixed it.
This happened to me to, freaked me out. Saw it in the blockchain, but not the Armory which would show up instantly with no confirmation and eventually turn green. Just never updated. I'll refrain from using the client since there are more bugs now than the previous version. I just hope I don't need to send any coin to anyone for something.
