I'm stuck at 281 points I've defeated all fightable civilians crushed everything I think I can crush squished all the corpses and am well short of the 300 required for growth 6 is there any failsafe?
Sorry, ignore that. Definitely thought this was the new one.
Generally, if you've beaten everything (all monsters in every area), plus all civilians and story bits, you should hit the amount (just over actually). So I can only assume there's 1-2 areas you may have missed. Or a couple of enemies you've just bypassed.
