Custom Unit Randomly Crashes Game

[Telecide]

Ughhh! I've been trying to figure this out for months. If someone could help I'd be very grateful! I've put a custom futuristic tank late in the game (it gets enabled with fusion). Sometimes the game will run for 50 more turns after they enter the game. Sometimes, the next turn after one is built there's a crash.

At first I thought it was something with the art files (I'm using Rabbit's tank), but I changed it back to look just like modern armor and it still crashes. It can go on impassible terrain and water and is in it's own custom combat group called "future units." Also made available to only one civilization. Any ideas?

Upload the work so someone can have a look.

For now I just have the Cyborgtank_Civ4ArtDefines_Unit.xml copied from the default modern armor file.

I'm totally baffled
Thanks

I think new unitcombats have to be defined somewhere. Why dont you just keep it as armour?
