I had some time to track and debug this situation in the code lately.

In short, I think I found the reason of the chain not syncing (and not moving), and generally speaking, can move it forward by making small temporary changes in the code (my local version).

However, there is an small[-ish] problem.. If I move it, I will create a fork, because my local wallet is synced to block 660564 only. To be able to move it from the most recent point, from block 674121 (which the node 95.217.78.169 has), I would need either access to that node, or a blockchain snapshot from that node. I believe this node belongs either to Matthihas, or to someone in his group.

So my question is - can someone prove zip the blockchain files (or make a bootstrap.dat) and give a link to download it? If I am able to get the latest chain version that way, I believe I can move the chain (not 100% confident though, but will try and probably will make it, as was the case on one other chain few years back).
