Can someone tell me what did I do wrong with this model?

[Locrito]

This model consists of a CageKart with 10 captured villagers inside.

Everything it has to do, is walk (and maybe die, but it's not important), but it doesn't even to that correctly. It was two errors.

1. When imported to the game, some of the textures inside of the villagers that should be inside the cage are scattered across the map.

2. One of the female villagers rotate along with the wheel when it walks e.e

I'm still amateur with model editing. Can someone please fix this bugs for me, or tell me how to do it?

It's not the textures that are scattered across the map but the models of the villagers because they are not attached to bone/s they have too. I tried attaching the vertices but the model is really damaged and I got an error in Mdlvis.

Thanks a lot, I managed to solve the problem.
