So, here I am with another idea.
once older critters have entered the world, the rooms can't go below the initial ones.

Lets start with 16 hunting rooms of Bears Skill 100-200.
1 month passes and less than 50% rooms are used on average.
the following month 25% of those rooms Bears get Older.
1st week one room Mature Bears, Skill 150-250.
2nd week 2nd room until month passes and all 4 are now matured.

2nd month Bear room had 60% utilization, so no change.

3rd Month Bear Rooms had 85% utilization, so they would expand seeking safer areas away from hunters. Adding 4 areas.
Mature Bears see 80% Utilization, so they too would expand. adding 4 areas.

the same cycle can continue to Adult Bears at 200-300 and ElderBears at 250-350 and Ancient Bears at 300-500.

this would give the world life, with changing hunting areas.... as well as an added danger to anyone scripting and not paying attention.

This would obviously take alot of coding, but I think it would be a nice improvement.
