it looks like the Nonca's bi-directional recording and scanning device may be looking at base skill instead of current since we can't equip it even though current skill is 1200 or higher.
Since there is no master metal gear form, we can't make the t6 sunscope. patch notes said that Noncas Fizzlebot in Aughendell would sell expert and master tinker forms, but he doesn't seem to have anything for sale.
if you kill tochak without triggering the 'look for tochak' step, the quest doesn't advance.
If you loot the sunscope and backpack with out triggering the 'look for tochak' step.. and leave them in your inventory when you kill Tochak again after triggering the step, tochak doesn't drop new scope and backpack and the quest still doesn't advance. you need to delete the scope and pack, trigger tochak, kill him, and then loot the new scope and pack. while this may not be a bug, it made for an interesting 3-kill adventure.
