PM broken?

[juanito]

Since I started playing there have been times when my BM kind of randomly mined either a lot, or very little of its base resource (be it sand or coal). At first I thought I wasn't paying a lof of attention to factors having to do with the PM (vassals and weather) but I'm starting to think now that there might be something broken.

With the same number of vassals and in the same weather conditions:

Our battle mine extracted 42 coal from the land.


then


Our battle mine dutifully churned up 9 coal.



:?

The first one, you hadn't checked your news in a while and it compressed a bunch of messages into one. The second one you checked quicker and just got one message.

Actually, the mining is coming in pretty steadily.

I see. That was confusing.
