I spotted this encoding error in the game config files, which will result in the engine calling non-existant ruin models via Destruction Effects.

CargoPlatform_01_ruins.F.p3d is the correct file, but in the config each Platform object which should be using those is referencing CargoPlaftorm_01_ruins_f.p3d
All of those objects also have the same typo in their Classnames & EditorPreview images.

The rvmat's the config's reference are all CargoPlatform_V1_multi.rvmat
The p3d's are all CargoPlatform_01_F.p3d & CargoPlatform_01_ruins_F.p3d
