Strange problem with object. Please help!

[camelman]

In my game you can use bombs, and the bombs use seperate explosion objects instead of a disappear animation. Well my friend decides to mess around with the engine's frame editor, and when I get back on the comp, the explosion object is all messed up and won't work properly. *Actually I didn't find out til' after I saved that the bomb object was messed up, otherewise I wouldn't be writing this right now!

For starters, all the animation frames are just transparent, I had to select the object via the object toolbar next to properties and workspace. Secondly, the animation editor itself is screwed up:

The pallete is tiny, the frames are there but the actual sprite is gone, I can't copy and paste any frames from other objects in there, and any time I try to import new graphics and make new frames, MMF crashes. It's crashed about 4 times whenever I imported something in this animation editor, so something is definately wrong.

Also whenever the bomb explodes in the game, it creates the wrong object in place of the bomb explosion, even though the bomb explosion object's code is still in the event editor.

Anyways...this engine was written in stone and a week later someone messes it up so I'd really, really like to get this fixed lol. Thanks for any help!

lol, well I fixed the problem. Since the bomb explosion's code was still there, I just made a new bomb explosion object and replaced the old bomb explosion with it.

Either way, I'd still like to know how that object got messed up. Any ideas?
