Great work on the patch othr!
But unfortunately the skybox fix in this hot fix patch doesnt work for me (i still crash as soon as someone fires a ranged weapon or something) So i have to do your first fix to solve the problem:
( load_mod_resource=skyboxes
replace with
load_resource=skyboxes
then go to 'Data' in the module's folder and delete the file called 'skyboxes.txt' from there.)
