Randomized map spoiled in embed of lobby invite link

**Describe the bug**
When you create a lobby, and select "Random" for your map option and share the invite link, the embed will reflect the map that was randomly generated, as opposed to being potentially a Dice image or a question mark, something not spoiling it.

**To Reproduce**
Steps to reproduce the behavior:
- Main Menu
- Create Lobby
- Scroll down and click on "Random" in map selection
- Click on the invite code to copy link
- Paste said link elsewhere (such as Discord), and view the spoiled embed

**Expected behavior**
Start the game and you will see the same map that was present in the embed.

**Screenshots**

(Removed hardware specifications as it is not relevant)

**Additional context**
Might need another player to test the bug as you cannot start a private lobby by yourself.
