Using CHECK is a good idea, I like that. Um......I've found that just loading the scenario into the editor and saving it somehow resetsORIGINAL: Lobster
I have gotten that message even when using the correct equipment file. I use a little gimmick to check that I am using the correct equipment file when working with a scenario. The people playing the scenario can also check to see if they are using the correct equipment file. Just take one of the Spare slots and put something in it that obviously does not belong. You could even name the piece of equipment CHECK. Then when you start the scenario in the editor or as a player and it gives you that message you simply look at the replacement list. If CHECK is there you are doing fine. If not, something is definitely wrong. You could even name the piece of equipment after the scenario.
BTW, that message needs to be modified so it gives you the name of the equipment file that is being loaded. Instead of the cryptic, 'using the wrong eqp file', it should say something like, 'using eqp file <NAME OF SCENARIO>'.
the matching of the equipment file with the scenario and makes the message go away when you load it into TOAW.
