Some time ago I downloaded Dueler's Mod 1.4, one of several that add a jetpack feature. Whenever someone uses said feature I see a gray square around the flames. I can see the fire and the smoke trails, but something else is missing. I've also noticed this same problem looking at holocrons. I can see the holocron and its base, but not the glow around it. It too is a gray square. Much more recently I downloaded JK2 Gold Edition again because I absolutely enjoy the "MagicBlades.pk3" file it comes with, but when I clashed lightsabers with someone I see millions of gray squares. I've reinstalled JK2 twice and failed to fix this problem. What should I do?
