I have a very weird situation with flexes on my model. All of them are fine in Blender, but after compile each shape key performs action of the one "above" it. They're kinda misplaced, but names stay on their places.

It's hard to explain, it's easier to check it yourself:

The same thing happend whith simple shape keys.
The only thing I can point out in the proccess of making these shape keys is that in the middle of making them I decided to scale the whole model (cus I would forget to do that later) and applied all transforms.

Any way to fix this? Or do I have to remake them?
