Looks like this might be a compatibility issue with Meteor Client. They are doing some modifications to the Minecraft code that Prefab then uses.

See the part of the log below which shows that Meteor Client is modifying something.

You can find their GitHub here: https://github.com/MeteorDevelopment/meteor-client

Closing issue.
