Summary:

When you press "Create New" in your worlds menu, "My World Templates" menu does not show up if you are offline (only "Create" button shows up) meaning that you cannot create Worlds you downloaded from the Marketplace unless you are online even though they should be available because you already downloaded them from the Marketplace.

Steps to Reproduce:

1. Open Minecraft while you are offline.
2. Click "Play" to open your worlds menu.
3. Click "Create New" button in your worlds menu.

Observed Results:

Only "Create" button shows up and "My World Templates" menu doesn't so you can't play downloaded Marketplace content while being offline.

Expected Results:

"My World Templates" menu should appear regardless of being offline or online.
