While taunting with the Angel of Death (or looking it far), a black string may appear on the medic's model ( http://i.imgur.com/m0UAJ02.jpg ).

This is a problem with the LOD's. For some reason, the LOD 2 and 3 has a strange black thing on the model attached. When the medic moves, a black string can be seen floating, along a strange "arrow" attached to his model.

This black string can be seen while taunting, while seeing the medic far away or not really far away (this are the LOD's, they will reduce the polygons when too far to not consume much memory to the PC).

Here is a comparison on the HLMV:

LOD 2: http://i.imgur.com/G1W34PR.png
LOD 3: http://i.imgur.com/Tct9yUv.png

I don't know if it's possible to fix this. I don't know anything about modeling, but I think just opening the lod 2 and 3 model and remove that weird object is going to fix it.

Thanks, I would like to share this because some people doesn't really know it's a problem with the LOD's and also alerting the item creators about the problem.
