Dagger Bug - can't attack at certain proximity

[Serancha]

This is an odd one. The uncharged normal attack does not work at all within certain distance of mobs. Screenshots to show the range that is the issue.

EDIT: This is not just planar blades, but ALL rogue daggers! (goblin blades as the only exception)

What is interesting is that the archers in Tinderin wilds are coded to stay that specific distance from you, so they will continually back up so you can't hit them unless you use a skill attack. The charged normal will work at this position, but it does not hit anything, so is useless to try.

The bug makes it feel almost like you are stunned, standing there unable to hit anything. Really bizarre.
