@Mongo101 Funny - I just noticed and changed the Wasp W file, as I noticed I used a mix of upper and lower case there. I found it when I returned from travelling and had edited everything yesterday, but have not yet posted it. Looks like you were ahead of me

Thank you for all your efforts and sharing your fixes.
Attached is going to be my 1.5.1.4 version of the CAB folder (this completely replaces the older JK_VariantsCAB - I'd delete or move the older one before replacing it with this version).
@Icewraith - Go to Nexus Mods and look up the Battletech Adjusted Mech Assembly Mod, this will allow you to collect 'Mechs based on Chassis base rather than needing all of 1 type. You can even parse out the ones you want to keep as unique chassis types. There are options in the Mod to allow it to choose the majority parts type or a percentage chance of any of the component parts, based on the # of parts from each chassis.
There is also a special version of the mod that Morph put together for the 3025 mod that will allow us to base it on Chassis name - allowing us to have unique custom 'Mechs for arena fights, but the salvage would all be the base Chassis type.
