After updating to 14w26c, and going onto my server, a lot of blocks are suddenly gone. Going to a pre-14w25a world backup is out of the question because extensive changes have been done since which I would have to redo.

Yes, you however did not state that before even releasing 14w26a. You stated that when 14w26c was about to be released already. Not much I could do at that point. Again, using a backup is out of the question, I spent an entire day creating land plots in an era, and I'm not going to spend another day doing that. It would have costed nothing to make the game simply convert the wronged blocks to their correct values, thus preventing corruption.
We explicitly stated that every world that was ever opened in 14w26a or 14w26b will be corrupted and you need to use a backup.
