Can't say for sure, but I'd suspect that it's been forking off and back on. There have been several disturbances in the network this autumn, including the pools, so that's quite plausible explanation. Maybe you could verify this from your server's logs. It's a good idea to occasionally check last blocks from the browser:
http://localhost:7886/index.html#/activity/fim/blockchain/latest
If that doesn't match lompsa.com (and several of the last ones are your account), you're probably on a fork (even though the server hasn't detected it yet).
It seems to show fork quite often but I don't know if there is much I can do about it.. At least now it seems to find blocks too :-)
