The type 6 windows are not working right on the saucer section for the currently released Nova variants. The Nova and Rhode Island show white boxes where the windows/lights would be on the saucer. One big one covers the name/registry number area. The Aurora/Quasar variants show a bunch of different colored lines that really don't look right, and in the Aurora's case the lines are floating above the saucer. The other window types work alright, though the Aurora's saucer seems to have minor issues with some window types (like type 5) flickering on the port side of the saucer, but that's a seperate issue. (Z fighting?)
I obviously can't test the Equinox class yet, but I suspect it'll have problems with the type 6 windows too.
