Hello Aslain!
Thanks for your work, you are reason why I stopped updating my XVM config, its really great to have all in one :)
Could you please update Gnome's gun sounds in your modpack to version 1.9461 with your next update? It fixes Panther 88 gun sound which i play quite a lot lately. It was released on 25.12.14 on curse.
Thank you.
Cheers
Fido
