Prerequisites

• 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.

Context

• Structurize Version: 0.13.104 Alpha

Problem description

Trying to play multiplayer on my server every time i try to join i get disconnected and console says Could not serialize com.ldtteam.structurize.commands.arguments.MultipleStringArgument@503ee031 (class com.ldtteam.structurize.commands.arguments.MultipleStringArgument) - will not be sent to client!
In Minecraft says badly compressed packet size.

Nothing in the logs either pointing to us as the culprits.
Please make sure: The minecolonies + structurize versions are the same on both sides.
You can try to execute /mc colony requestsystem-reset-all from the commandline to see if that helps anything

com.ldtteam.structurize.commands.arguments.MultipleStringArgument@503ee031 (class com.ldtteam.structurize.commands.arguments.MultipleStringArgument) - will not be sent to client!

this is certainly not related to the login problem. But I'll check the log for more info.
