When you using scanner fishing rod cutter and then use melee (E) after pressing second mouse button (right) you back to weapon.
This was reported bug after melee 2,6789..... and once fixed and after pressing second mouse button warframe back to scanning fishing etc
(off course that was not perfect because if warfame had only melee that dos not work)
Now after last patch this bug return, and this is really annoying and totally destroy any fun when you want scan somethin
