OK, That is no problem. This file is actually "attached" to another object, that is not being used. Just the texture itself is being used. We can use it "as-is", and will not effect he game any. I can not understand how I could miss a node. But if you know how to do the node setup, go ahead, and there will be no problems.
IF...I say again... IF there are any problems, tell me again, and I will fix them. It could happen, that after I copied the level, and then draged it across the screen, that something got moved. I do not think this is the case, but everything is possible.
Also, there is no double damage. To tell you the truth, I forgot it. If you want this in there, I can tell you where to find it, er.. I think. I have never put one in any level b-4.

***EDIT***
I went to the editor, and fixed the Pathnode 5 problem. If you want to do this on your own, or do not care what happens,
DO NOT DOWNLOAD THIS!!!
This now has a newer version number, and we should be careful here.
