Describe the bug
Trying to utilize the teams feature does not work correctly. After setting everything up on the server I am planning to use, I start a round but the main teams menu does not appear. Checking the console on the client gives me the following warning: [Client thread/WARN] [flansmod]: Problem in landing page!

To Reproduce
Steps to reproduce the behaviour:

1. Setup teams and begin a rotation
2. Try to open the teams main menu

Expected behaviour
The teams main menu should pop up and display the "Choose a team" screen, allowing players to join any ongoing rounds. Instead it does nothing

Versions (please complete the following information)

• Forge: 1.12.2 - 14.23.5.2854
• Flan's Mod: 5.6.0-beta.10

I am having the exact same issue and I am running Flans 1.12.2 as well.

I have the same Issue running flans mod 5.5.2 on a 1.12.2 Server

@jamioflan this seems to be a important feature, according to the website. So it would be nice from someone with Java knowledge to try and fix this.
