Default items appear instead of custom items

I registered a custom item in tiger gather, but the normal item is dropped

How did you manage to get a custom item into the gathering configuration? Normally custom items are not supported for gathering and you shouldn't be able to add custom items to the configuration

I was able to use it normally with the latest version.
Click gathering


Click any


Click ADD ITEM


Clicking Custom will display your custom items, which you can select to add as normal.

There will be a fix for this in the next update
