Wubz I do not experience any of those bugs in the recent patches, other than the sydney mem leak (which may be fixed now) , I am not sure about the bank though, as I do not do heist, but i'd presume that those exploits have been fixed by now too. As for the map and population, AU really isnt much larger than Altis, but AU is definitely more fun to romp through than Altis-Paltis. The only areas which I been camped is the weed field (suprise!) Ive been hit at the diamond mine and processer as well, but besides that camping was not a problem for me when there was 60ish people playing regularly.
The main issue of aussie life is that no one wants to play it due to superficial reasons, like the maps optimization (its brand new, give it a break! Do you remember Beta Altis?????), or people like me who just lost interest after the population dropped below 15.
