catapult range?

[Seven.the.Hun]

tried to enable the hun catapult range...but CTD when its next up in the queue and i click the end turn button...
i missed a step somewhere, what must be done to enable this kind of building for the hun faction? i was aiming to get it working and able to produce the typical onager unit.

well i figured out the unit card stuff so that things show up properly and no ctds occurr.
i thought i'd save a little space and add in a little question relating to the archery buildings and units and perhaps someone will see it.


anyone know off hand the max range of all 'projectile' units? i cannot find it.
i think for javelin troops its 73, and for archers its 187, not totally sure though, and i dont know about onagers or heavy onagers or slingers and the other stuff though.
