Unable to import Madagascar kartz (PS3) .nif files

[NitroStorm07]

Tried to import a .nif file from Madagascar Kartz and it seems to have a problem with "SIFBtPhysicsObject". They open fine in noesis but the .kf animation files seem to not work on noesis.

Python: Traceback (most recent call last):
File "C:\Users\User\AppData\Roaming\Blender Foundation\Blender\3.6\scripts\addons\io_scene_niftools\dependencies\nifgen\formats\nif_init_.py", line 297, in read_blocks
block_class = niobject_map[block_type]
KeyError: 'SIFBtPhysicsObject'

During handling of the above exception, another exception occurred:
