[ano]

I may add a point here. In a current game as LA C'tis one of my D4 Sauromancers got diseased. I was really surprised (yes, it was late winter and no disease site there) but just ignored it. Perhaps another bug.
I archive all my turns so if anyone (preferably the devs) is interested, they are available.

Also, another thing here (was discussed recently). Now I'm absolutely sure that afflictions are not divided into "old-age" and "not-old-age" meaning that you can't heal affliction with healers when your unit has old age, no matter how this affliction was received. For example, you have absolutely no chance of curing old mindhunters from feeblemind unless you remove the old age somehow.
