I find it kind of annoying how you wait 7 days and spend 100k and rarely get any calls for the expansion.
I got my first forestry (excuse me if I call it a brush expansion) 4 - 5 weeks ago and I only ever got 2 calls. I thought getting a second brush expansion would increase the brush calls. I got one 2 weeks ago and I haven't gotten another one since.
I feel like that if you pay and wait for an expansion, you get more frequent expansion calls. Especially SWR at least around where I live they're pretty common.
(If this is a thread already I havent seen one. Please link it if it does exist.)
