Prerequisites

• I am running the latest alpha version of 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.

Context

• Minecraft Version: 1.16.1
• Structurize Version: 0.13.43-ALPHA
• MineColonies Version (if related bug):
• Related Mods and their Versions: Forge 32.0.108

Expected behavior

When I right click the building tool on a solid block, the GUI should pop up.

Actual behavior

When I right click the building tool on a solid block, the game immediately crashes and shows the error "The game crashed whilst loading entity nbt Error: java.lang.ClassCastException: net.minecraft.client.world.ClientWorld cannot be cast to net.minecraft.world.server.ServerWorld".

1. Stand in front of a solid block
2. Right click the block while holding the building tool
3. The game should immediately crash

Gonna leave this open since it's only temporary fix which will make IronGolem (problematic entity) not render in structure previews.
Please try 0.13.44-ALPHA, it should not crash anymore
