The model is fine, the problem is Hive's "view in 3D" button. Some versions of Retera Model Studio recently were saving in a way that isn't supported by the "view in 3d" button. But the model is fine and works ingame.
If you open the model and then save it again on Retera Model Studio 4.5f with the new setting unchecked in the checkbox:
View attachment 436238
Then this model can reformat instantly to "View in 3D" button format and will preview again OK. Because the model is fine, it is only "View in 3D" software that is broken.
