Not a game crash but some models will not show.

When a file is missing it can cause various issues, from nothing what so ever, to making the map look weird to crashing (either at startup or at some point in the game, depends on the code)

Then again. NOT ALL NEED TO BE FOUND and here is why.
Some maps (usually over long time of development and updates) have files they are no longer using, thus they are just files that are never used and are free space if you just delete them.
Dota has some un-used files. IIRC they had a model for the item "Satanic" and at some patch got a new model to replace it.
The old model stayed in the map but was never used since. So if non of the tools find it. It is okay, nothing will happen.

If you know what file is missing, for example, the model of some doodad or item.
You can open THE ORIGINAL MAP in MPQEditor > Tools > W3X Name Scanner > Live

This will play the map in a mode that allows MPQEditor to see what files are being called.
don't click me / use the item your model is missing from.
And MPQEditor will find that file name.

Thank for your explaination !
