Hi guys, can you please check if by any chance my patch makes things better for you?

I have made my best to homogenize Serge's files with settings and internal structure of analogue stock files (removed unused chunks, sorted chunk indices as per their usage order wihin each file, removed unused AO map channels, fixed some wrong material assignations). Moreover, I have remapped the Id's of all the nodes, just in case your crashes were caused by an Id conflict, I have put rocket's smoke effect in an external file and I have linked it to the rocket model as trail effect, I have made the rocket to use launch and fly by sound effects
from GWX (hope it is okay

), etc.
I hope it works. Let me know
P.S: I am now working on a better British 3-inch rocket model. It should be ready before tomorrow
