Help swapping item collections (itmc) in the .scnr insolence

[woofer999]

I like all the guns in the game. So when I started putting single player weapons (fuel rod, jackal shield) into the game, i wanted to keep the original weapons in the game. So I didn't swap the weap tag under itmc, i just duplicated the itmc, renamed it, and then swapped the weap. So I copied the smg itmc, changed smg to jackal_shield, then replaced the smg weap tag with the jackal_shield weap tag. Then i went to the .scnr and replaced the sniper rifle's on the base's of coagulation with my new jackal_shield .itmc. Now every time I play the map, it freezes within 20 seconds, and sometimes it won't even load. i've tried this on multiple maps multiple times, but it never works. is there something i'm not getting? thanks for any help
