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.

-- I am running the latest release version of MineColonies and the latest alpha version of Structurize for my Minecraft version.

Context

• Minecraft Version: 1.16.5
• MineColonies Version: 1.0.0-RELEASE
• Structurize Version: 0.13.219-ALPHA
• Related Mods and their Versions: OptiFine(1.16.5_HD_U_G8)*The stack trace doesn't mention any other ralated mods, except this.

Expected behavior

I don't know what will happen when I switch to the Guard Scepter from Build Scepter.

Actual behavior

The game threw NPE:Unexpected error and crashed for 4 times.
1st: The first crash, didn't notice what causes the crash.
2nd: Tried to connect to the server, then client crashed.
3rd: I connected to the server, and instantly teleported myself to another place then died. Client ran prefectly, but when I
switched to the ScepterGold, the client crashed in the same way.
4th: I changed my character-dat-file, modified "SelectedItemSlot" from 6(ScepterGold) to 0(other item), then joined the server
and moved ScepterGold to my inventory. But this time when I switched from Slot6(Nothing) to Slot7(ScepterGuard), the
client crashed in the same way.

Steps to reproduce the issue

2. I scheduled many buildings using ScepterGold.
3. I have tried to use the Guard Scepter to set guards' path, but made no effects(one of possible causes ).
4. Related action is retold in ##Actual behavior.
