Issue with automatically pulling in new skins

Is there an issue with the plugin pulling in new skins - not seeing them available to skin the items.

These are both set to true

"General settings": {
    "Generate/Check and add new skins accepted by developers or made for twitch drops": true,
    "Generate/Check and add new skins added by developers [ For example, a skin for hazmatsuit ]": true,

No problem.
The plugin will automatically pull up new skins as soon as they are added to the server memory by the developers.

This happens once a week or a month.

Changed Status from Pending to Closed

Changed Fixed In to 1.5.1

So when facepunch add new skins they don't appear in the list automatically? have to wait until they are added into server memory somewhere?

Yes.
Developers add them to the server memory once a week to a month.
