+BoneyBoy. Currently at 7x bonus. It's impossible to go past that, since closest new job(to get achievments to improve bonus) is arts and it requires 20 in angst and wisdom. And 20 in wisdom is about a week or more away. Maybe, make achievements re-achievable or differentiate - i.e. getting last job in career gives 1.0 multiplication instead of 0.1 or smth like that.
The reason for wall is that upgrades are additive instead of multiplicative. Say basically you have 100gpc. Then you buy upgrade x3 - you get 300gpc. after that you get upgrade x5 gpc -your new gpc is not 5x300=1500. It is(1+3+5)x100=800 this make later progress ridiculosly slow. Please fix(or add more content =)
Also waypoint problems when lice get resources to far away point instead of close one. Also it seems that fight is somehow flawed - if if get to fighters they sometimes work worse, when together - like i can clear wasp nest with two big guys, if i send them one after another. But if I send them together they die.
