rate of spawn aside the no-spawn-zones just do not seem to be working anymore. I have a one workbench sized farm with 2 benches protected it all terrain raised up and they pop up on it (and can't get down) so if they get aggroed they trash the crops. That was not an issue some time back.
I can't complain though, so far I have lost like 2 wheat plants and gained 200 deer meat, 100 boar meat, related skins and junk, 500+ wood/stone/resin/dwarf junk, a half stack of needle, a full stack of dark iron, 20 or so ooze (invasion!), and more. Every morning is a 2 trip cleanup job.

The rate does not bother me, but I can see how it could. You can't do anything your first trip into the BF from it all, unless you start fires around whatever you wanted to do.
