Hi, just discovered these mods recently, don't know how I missed them before, they're amazing!!

Just passing along that I'm having some issues in the buy menu. I have both the Challenger mods (with the D&H loaded after the original), in a vanilla testbed map, no other mods loaded, build 35300. It says 15 variants, but all the D&H models have at least one duplicate, some only as purple squares. For example #1531 is listed 4 times, 2 as purple squares. Screenshots:

As well one from the base mod has crazy high weight. The D&H are all 276 t (metric) and the base are 284 t except for one of them that's 487 t (1+ M lbs!).

Cheers!
