Model distorted after opening file

[mapika326]

So when I open this file, any version of it, the model appears to be suddenly distorted, even though it was fine when I last saved it. Every time the distortion is a little different, sometimes it's even completely fine, though that's pretty rare. Only some edit poly modifiers are affected by this, so they seem to be causing the issue, but I'd like to keep working with them since I'm not done with the project and would like to have the option to change certain things afterward. Does anyone know why this happens and how I can fix it?

Looks like selection or topology was changed in one of "lower" modifiers.

A bunch of EditPoly modifiers can be good for trying things out, but it is not non-destructive since you can't modify geometry that comes earlier in your stack.

You said that sometimes it looks normal. I suggest to collapse the stack when you will get the model in such a state and continue from there.
