Prerequisites

• I am running the latest alpha version of MineColonies and Structurize for my Minecraft version.
• I checked the MineColonies/Structurize wiki and made sure my issue is not covered there.
• I made sure that this issue is not a duplicate of any existing issue.

Expected behavior

when removing a disease from the server config, one of the 2 cases are reasonable:

1. the colonists currently with that disease is cured
   or 2. the colonists that were sick are still sick but no one else can get that disease

Actual behavior

The save file crashes when the world is loaded. Re-adding back the config fixes the issue.
once everyone is cured, disabling the config works and the save no longer crashes.

Steps to reproduce the issue

1. get some colonists to have small pox
2. save and quit the world
3. remove small pox from config
4. launch the world
5. crash
