SouthHollow automatically distributes a custom designed resource pack to players to enhance their in-game experience.
Sometimes, the pack doesn't load correctly because the client has it disabled.
Enabling Resource Packs
Find SouthHollowMC on your server list, select it, and click on "Edit Server". The following screen should appear.
Click on the "Server Resource Packs" until it says "Enabled". Finally, click done and then join the server.
