Was able to trade witch engrams for red border variants of the standard witch weapons. When I dismantled 4 of them they gave no progress, as I am new to the game (friend had told me dismantling gives pattern progress) I did not know it was messing up, I removed the last one manually in the "details" section and that one gave pattern progress which made me realize none of the other 4 gave progress... Did I miss something? Or did it bug out?
