Tremors occur three times before each eruption, but sometimes its only two?

It also looks to me that sometimes its 3 "tremors", sometime only 2 and sometimes maybe even 5 ( if you quit the game and load it again later).

Maybe this is just an impression. ( a mod counting the "tremors" and displaying the count can help ) Possibly its a bug.

However maybe this randomness is by design, not an actual bug. Just don't know, - the clarification is appreciated ;)

Also I think that sometimes the hound attacks counter is interfered with "natural disaster" counter, or something like that.

I'm also positive that hound attack counter sometimes gets reset upon the change of the season. Which is OK with me, though illogical.
