This is more of a Removal of Feature request...
Please remove the key binding for New Campaign.
I have seen many bug reports where people's campaign randomly vanishes and a clear grassland is all they are left with. This has happened to me a few times and I have FINALLY figured out what is going on! The menu command: New Campaign is tied to Alt-N. So a person can too easily have that occur and insta-wipe the current session.
I do understand we are now given a prompt to save the current campaign before creating the new one, but one can easily get that prompt and hit return long before they knew what they just did. In fact, I wiped a session this past weekend doing just this and I am a long time user.
Are you sure this is what you hit? I just want to make sure something else isn't wiping without a warning because...
Another long time user that I game with wiped a campaign in similar fashion this last week... and I've, personally, never done this or see it happen in all the years I've been using MT. He wasn't exactly sure what key combination he used (but he was using one). He said that he *did not* get a confirmation window (though I suppose it could have happened fast enough that he missed it... defeating the use of a confirmation box if that was possible).
At any rate... I concur with your request.
No need for a key binding for this feature. It's, potentially, too destructive.
I just hope that this is what caused the issue and that there isn't some hidden key combo.
NOTE: I will, however, remind you what I ended up reminding him (too late to save our session)... *IF* this happens, immediately open a new instance of MT without closing the one you just wiped. The second instance should see an active "autosave" (i.e. crash recovery) file and ask if you want to use it. If you have your auto save set for the default 5 minutes you should not lose much.
EDIT: I just tried ALT-N and I could not get it to wipe a campaign... will continue testing...
EDIT 2: OK, I had to hit "ALT-F", then "N" to get the Confirmation Box for a New Campaign. Which leads me to believe that this is not what's causing the problem. More investigation of what key combination could do this without a confirmation box should be done.
