Hi Frau Kaleun. I noticed in S3D that the Averof always had node for Lifeboats & Debris in the val file:

So you can open val files in S3D for check the difference between one and second Averof file, [id's of the nodes etc..]. I don't know what changes Wreford Brown done in this file, because I don't seen this file.
[EDIT]
I think is better to use file from Lifeboats & Debris mod. These files can be the same, but I'm not 100% sure about this if I can't see them.
