Unit graphics while using mods

[Reznaak]

I've been having issues with mods. In the Next War mod that came with the game the assault mech graphic likes to disappear (but the unit stays in the same place). Sometimes I'll see it floating upside down under aircrafts stationed in cities.

When I use user made mods I have a problem with unit graphics defaulting back to the default look unless I have them selected. For an example, I was playing a mod with dwarves and when I have dwarf warriors selected, they look like dwarves, when I don't they look like the default civ4 warrior.

Is there any way around these graphical errors? They are very distracting.

Thanks.
