i tried shooting chop but it won't let me, i also switched from trevor to franklin after a mission where he drops him off at his aunt's home and when i was franklin i was inside his aunt's home and there was no way he could get out, tried both doors with no luck, this is obviously a bug in the game, it shouldn't of let me switch to him, had to switch to someone else, play the game for a while then switch to franklin who was at his other home.
i also tried beating franklin's aunt up whilst being franklin and it wouldn't let me.
in fact i have tried doing this a few times with certain characters and other people in the game and it won't let you.
the number of missions i have been doing and side stories and the amount of money you get is awful, i had to drive some drunk retard halfway across the map to the cult place for a lousy thousand bucks, one of the random events.
only decent way to make money is from lester's assassination missions and doing the trades he suggests with all 3 characters before starting the mission, so you need to find a guide online and find out which stock it is before hand and then buy it then switch to franklin and go meet lester.
the way the game is set up is so it's nigh on impossible to make decent money, as i tried switching before an assassination to invest but it wouldn't let me so you need to do it before you find out which company you should be investing in, so you need a guide otherwise you make nothing with the other 2 character's then.
got michael up to $1.5 mill, franklin has around $300K but trevor only has like $60K.
i stupidly bought some properties which don't make you any money (garages), and the properties that do make some money make pennies and you constantly need to do side missions to protect them or you lose the cash inflow.
like i said the game is set up so you cannot make hug money quickly.
it's constant grinding in order to prolong the game imo.
