Season 7's release was not bug-free. The game's executive producer was ingame last night in the Redalert channel assuring people that they have programmers working on a fix.
Name one season that wasnt a bugged nightmare. Every season I can remember brought tons of bugs with it due to lack of testing. Cryptic has never really been one to test a product much before releasing it. How long do you think it will be before the newest incarnation of voldemort is fixed? Its happening on a wide scale basis now. How game breaking is it to have an escort running EWP3? Have they even aknowledged this problem, much less put any devs on fixing it (again)? Seeing as how its NEVER has been completely rooted out of the programming and has been around for years, I kind of doubt it.
