Custom Model works correctly in War3 Model Editor, but NOT in World editor

[Kyginbo]

Hello, I've successfully added several custom models to this map the same way and when in War3 Model Editor, the model is perfectly fine as per the 1st image. But for this one specifically, when I import it into World Editor, it turns into the mess in the 2nd picture and crashes the program if I try to interact with it. I have tried loading the model onto a fresh map and without the textures linked and the same thing happens there. Does anyone have some suggestions?

Probably because the model is in mdl format instead of mdx. Try converting the model with this tool:

MDLX Converter

Converts between MDX and MDL files. - Click "Convert" and choose one or more files to convert. - Click "Repeat" to do the last batch over again. This is useful if you had an error in your MDL and just went back to fix it. - You can also click and drag files onto the program from...

Upload it in the Hive's model sanity check to see if returns critical errors

Converting it made no difference, but running the sanity check returns a lot of errors. Lots of "There are no vertices attached to this bone" and "Missing opening track for sequence "Attack" at frame 2916 where it is needed."

Can anyone help me understand how this could happen?

Those are not threatening errors as far as I know, bones without vertices are just "dead weight" but they're not detrimental, as for the missing sequence, it shouldn't cause crashes either
