CI timed out again.

Getting this, error message sounds super weird:

2017-08-21 13:53:06  Encountered error during block restoration: Snapshot contained too many blocks. Expected 5000, got 4960

Should be probably self.fed_blocks + num_blocks in the error message not self.fed_blocks.

Not sure if this is related, but never noticed this earlier. Once the snapshot restoration fails, the total amount of requested snapshots increases:
