When Windows Glow - Raven Rock, Animated Morrowind (not sure which one), and Antares Big Mod are used in conjunction with one another, the animated NPCs and the scouts from Antares' Mod appear outside the Raven Rock bar in the void surrounding the interior cell. Has there been a fix for this?

Thanks. I'll give it a try and return with the results.
