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.

• Minecraft Version: 1.15.2
• MineColonies Version: 0.13.451
• Structurize Version: 0.13.94

Expected behavior

• No crashes

Actual behavior

• Loading the mod on my server caused it to crash.

Steps to reproduce the issue

1. Load the mod on a server.
2. Crash

Logs

• Crash Report

Notes

• Add a comment if you have any insights or background information that isn't already part of the conversation.

So, I double checked on this, and actually this mod:

at com.fuffles.justanotherheadmod.common.item.AnotherSkullItem.func_150895_a(AnotherSkullItem.java:344) ~[?:1.0] {re:classloading,pl:runtimedistcleaner:A}

Is causing the crash. Please report to them

The previous version of minecolonies doesn't crash with it though. Do that mod need to change something?

Yes, we've added code to detect all subitems possible to detect modded fuel that uses nbt data for example. Now that item crashes when asking it for that kind of data

Ok, thanks
