...ah I see, this isn't even the right thread. Lol, my bad.

Looks like we're headed in the right direction 
Downloading it now and giving it a shot!
Edit: Interesting. I'm getting the exact same results. I use the Fire Extinguisher, and it just breaks really fast. You can't repair it still, and it has 960 C02 ammo loaded into it. Scrapping it gives you all that ammo. How are you supposed to repair the fire extinguisher normally?
Edit 2: I managed to fix repairing it. I went into "items.xml" and found
<property name="RepairTools" value="RepairKitAutomaticRifles"/>
I then replaced it with;
<property name="RepairTools" value="resourceRepairKit"/>
and that did the trick.
I don't know how to reduce its ammo drastically down or how to stop it from breaking after 10 uses... But I'll keep having a look into it.
Edit 3: After a bit of tweaking, I changed the degration rate here;
<passive_effect name="DegradationMax" operation="base_set" value="1000,22" tier="1,6"/> <passive_effect name="DegradationPerUse" operation="base_set" value="1"/>
And I double checked and since CO2 isn't used for anything else, it's safe to assume that possessing CO2 is only useful for other Fire Extinguishers. I changed the stack size from 50 to 1000.
Since it degrades at 1 per use and the degradation max has been increased (at least) to a 1000, I think it's reasonable to now have the ammo be in a stack of 1000. What was your original goal/purpose for having it in stacks of 50?
