small graphical glitch with psi amp:
that guy there in the armored coat is holding a blaster pistol and a psi amp.
there´s a small artifact following him around, depending on his sight direction.
(circled in 2nd picture...)
its not on the same tile. if he moves, it follows him.
its not on anything else, just the psi amp.
EDIT: looks funny though... kinda like he´s holding a really long fish and thats the tail
