A scenario I made many years ago won't open in scenario selection.

[DRG]

As I said any CMT that includes the slot number was modified using EditPlus so that adds up to 522 CMT's in WW2 plus all the ones in MBT and every one of them is still 200 bytes but as well some scenario and map names were made larger than the game normally allows using the same editor. A good example of that is....

18 Grudge Match at Kapelsche Veer 1/45

if you try to save that in the game you only can get to

.......just saying you can edit CMT's with a text editor and even make them longer than the game normally allows and the game won't blow up but it could be you need a good text editor that only adds what you want added.

( or maybe I've just been lucky for 20 years or maybe I just know what I'm doing )
