No. It's only been 4 weeks since we reported it to them. The week before Forsaken dropped people noticed it and Bungie said it was an issue they were "investigating". But Bungie had plenty of time to trackdown and squash the Telesto Exploit at the Well. Funny how things don't change since D1 Beta dropped. They can issue a patch within a week to fix any exploit where we don't play the game like they want, and then take months or even years (i.e. Fire Fly game freeze / crash which took YEARS for them to address in D1) to fix stuff that prevents us from using weapons effectively.

Some issues are more easy to fix than others.

True. But it only seems the issues that affect how Bungie wants us to play the game get priority.
