Game designer Gabe Amatangelo posted on the official forums to announce the fix and explain the problem, which was introduced with this week's update 1.1 to the game. It was caused by players managing to enter and camp enemy bases when "under server load", which was not intended as part of the design.
BioWare's also reducing the population cap on the zone to improve performance.
There will be no general rollback on the Valor points earned since the exploit was found. However, associate community manager Joveth Gonzalez added, "we're definitely aware of individuals who took extreme advantage of this situation and we will be carefully evaluating and taking action as necessary".
