Dynamix' Dave Moore updated his .plan with word that the recently released Starsiege: TRIBES 1.7 (which was supposed to fix palette errors on 3dfx cards) is causing palette errors on 3dfx Banshee based boards:

Erk! Ok, there have been reports of palette problems on 3dfx cards with only one TMU (Voodoo Graphics, Rush, Banshee). Mea maxima culpa, all my fault. I goofed a logic test (Morgan's law? Something like that. The one that goes ![A && B] => [!A || !B]). We're aware of the problem, and a fix is in QA at this time. This is especially embarrassing, since 1.7 was supposed to fix a palette problem on Voodoo 2's and Voodoo 3's. Sigh.
