This happens in %20-25 probablity (to me). I have 1-3 range weapons. When I get closer to the enemy with grip-teleport-charge, my weapons sometimes continue to say "not-in-range".
In the pic, I got a screenshot of a time that me and foe had 6 range between, then I charged and tried to use my weapons.
p.s. I tried to move between submenus, doesnt solve it.
