Probaly because of mutiplayer and or split screen? Maybe even due to the horribal chain control system they use for consoles...
Actualy theese problems GM4Him had allready covered in his past suggestions that are somewhere in this mess, so maybe you missed those.
Both multiplayer and split screen problems are tied only to amount of PC players ... So IF (and i know its a big if) Larian would allow us 6 members, party with limitation of 4 player max ...
There would be no problem at all.
If my comments bother you, there is nothing easier than telling me to stop. I mean ... I won't ... but it's easy to say.
