Server constant LD but not LD issue.

[ld420]

Fairly recently I have discovered after a random amount of time, everyone loaded on my screen "blinks" out of existence. Afterwards, its like being LD. I cannot target anyone, and if I cast a spell it never casts. You cannot sit after casting this way either. My meter is green, and I do not show disconnection, but it behaves that way. I am monitoring my connection to the net, and it does not waver. Only way it seems to solve this is to close client altogether, and re log in. Please help, I cannot play this way.
