if you have problems in casual: i don't agree that chickens are the best way to go; there's slow return on them and Kerae's approach tends to involve a lot of luck in search (or more likely, a lot of browser refreshes). start as either noble, hunter or sherriff, don't upgrade anything except the two house upgrades and the smithy (mostly for mod days). save your money to upgrade your weapons and buy good mods, and if possible get either a duelist or hunter npc to max engineer party skill.
neosapien: trade your sniper for a ranger to get breed (and invest in chickens), or failing that, for a militia and get taunt. max either skill. and make sure one of your party has active maxed.
does the new update prevent mostdays survived for games saved before the update? my save (lvl 66 hunter w/ rapidfire bowgun mkii) has been enhanced by the 30% museum income update, but is it across the board?
