Not being able to change the NPC skin for the Gamesinv NPC

[moeedlol]

[22:15:37 ERROR]: [SBA] Unable to retreive skin of notch: NULL
[22:13:01 ERROR]: [SBA] Unable to retreive skin of mxeed: NULL

They just give me "NULL" and I don't know what this means. Any way to fix this? Is this a bug?

I would have to check about this error, but note very few people actually use Gamesinv NPC as any npc such as citizens with a /sba gamesinv solo (would replace a solo npc) and as such it's much more stable than the internal NPC of the plugin.

I would however ask you to answer those questions:
Did you manually try to change the skin of those npc or is it the default skin?
Are they still being shown with an incorrect skin or completely gone?

Thanks, it will help diagnose the issue
