GatherManager is correctly doubling dispenser rates but not pickup rates. For example, hitting trees with rocks went from 20 to 40 per hit, but picking up hemp remained at 10 cloth instead of increasing to 20. Every time a player picks something up the following error appears:

"Failed to call hook 'OnCollectiblePickup' on plugin 'GatherManager v2.2.78' (Object reference not set to an instance of an object) at Oxide.Plugins.GatherManager.OnCollectiblePickup........"

I've tried several past versions of the plugin and have had similar issues. I have a hunch this has to do with a Carbon incompatibility, as my server is Carbon based and I see Oxide mentioned in the error.
