BG2 shipped without the (brown) lizard man weapon overlays, which did get included in IWD. These are included in this archive, but if you just want the missing weapon animations in a game without the rest of Infinity Animations and/or that 90mb archive, you can extract the attached archive to your override folder. This will also fix mod issues like this one. You can reproduce this in an unmodded game via CLUAConsole:MoveToArea("ar0420") - if it doesn't crash, notice the lizard men wield halberds but you can't see them.
