Sorry for the double-post in advance.
Some of you might have noticed the wallets inability to sync for the last 6 hours or so - that Is entirely my doing.
No, the wallet is not broken and it is still perfectly capable of synchronizing - there just hasn't been generated any blocks for the last 6 hours.
I went through the code and noticed that the new algorithm for difficulty retargeting is, although whole-heartedly meant to be better... but in fact it's not.
Doing a few preliminary tests (offline) showed that difficulty retargeting is extremely agressive when a lot of hashing power is thrown at it. I wanted to bring this into light while also showing the downside to this new algorithm.
So I threw all my hashing-power against the network and thus got the difficulty for a n-factor 13 block up to something in the vicinity of 1.7k compared to the roughly 220 it was before. Don't worry, when the current block is solved, difficulty should be down quite drastically - although that might take some time.
TL;DR - devs... fix your new diff. algo.
