* Fixes money refund problem when selling silos - the money refunded when selling a silo was being credited incorrectly. This has been fixed. In order for a fixed version to play with an unfixed version - possible when in a multiplayer game - a special command line option must be used. Pass the parameter "-o" to the C&C.EXE executable.
* Cost of Nod turrets changed to 600 credits - this addresses a balance issue regarding Nod turret production.
* Nuclear crate collection allows Nod nuclear missile - collection of the special nuclear crates in certain Nod missions will allow a nuclear missile to be launched from the Temple of Nod in the final mission of the game.
