Subject: [PATCH] Fix client rendering skulls from same user
|
|
|
|
See: https://github.com/PaperMC/Paper/issues/1304
|
|
|
|
Changes the UUID sent to client to be based on either
|
|
the texture payload, or random.
|
|
|
|
This allows the client to render multiple skull textures from the same user,
|
|
for when different skins were used when skull was made.
