I set "Condition" from default to 500 and no change.  I tried lowering the number to 10 and no change.  Anyone know a fix?  

Are you making sure you gave yourself permission to use it?

Merged post

Is this in regards to crafting weapons? 

the permission I used was firearmmodifier.1 .  The magazine size changes and if I do InfiniteCondition to true it works.  But I want damage just slower.   Not sure what other permission I am needing.

I even craft new weappon after changes and nothing changed

"smg.mp5": {
"PermissionSettings": {
"firearmmodifier.1": {
"SkinId": 0,
"MagazineSize": 60,
"PreloadSize": 8,
"Condition": 500.0,
"InfiniteCondition": false,
"InfiniteAmmo": false,
"DropOnDeath": false,
"WeaponName": "",
"AmmoType": ""
},

I've tested it on my server and there are no problems setting any condition level and then crafting the weapon.

So perhaps you have a conflicting plugin?

As far as infinity condition goes that is indeed intended as is.
