[help] Error creating lightsampling!

[cat]

When I want to create lightmaps for a bunker static from mestia this happens

[LightmapGeneration] : Error loading lightsampling file: objects/staticobjects/pr/bunker/bunker_large_wreck/Meshes/bunker_large_wreck.samp_02
[LightmapGeneration] : Error creating lightsampling!

First I was thinking that was because it is a breakable object and that they do not have lightmaps. However I saw on mestia that they actually do have them. So why wont it lightmap??
