That's weird, usually there were about 2 forests per consumer and I can not remember changing the numbers. 10 forests per consumer is a bug.
I'll take a look in foreseeable future.
I also sometimes get this problem. And in my case, (I don't know if it happens elsewhere also but I think it might; plz tell

) there are less of other industries. MUCH less. Forest, forest, forest everywhere with few other industry. And also (like this, ) only 1/2 sawmill (maybe because I play on very small maps

but the effect is basically same.) Very woody.
