I am unable to dismantle the weapons I started the game with. I used a Spark of Light to level up to 30. I was able to dismantle the light level 100 armor pieces I started with. I do not have any issue dismantling any other piece of equipment. I am aware of the issue/feature that prevents dismantling when the controller detects any input. I do not have any drifting from my controller and am fairly certain that isn't the issue. I've attempted to store the two weapons but was not able to do that. I recently updated Destiny 2 after using the Spark of Light but I am not sure if that plays a part in this issue. The weapons are Origin Story (Auto rifle) and The Last Dance (sidearm).
Hello, and thank you for your report. We are investigating a fix to this issue.
