Modpack Version

Expert v1.1.2

Describe your issue.

You can dead-lock servers/worlds when a Create schematic contains a Travel Anchor. I don't think it has to be named.
It will give you a Stackoverflow error and then dead-lock the world because whenever the Schematic Cannon containing the Schematic is loaded again, it will crash.
I solved it by forcefully chunk loading the position (this made the server crash again because the block got loaded) and when it restarted, I spammed a setblock command when the world loaded and it got rid of the Schematic Cannon.

This is of course a mod issue but this is good to know for modpack players too.

I will provide the initial crash log when it loaded the crashing Schematic for the first time and the crash log that occurred when loading the position again after the server restart:

Did the issue happen in singleplayer or on a server?

Server

Thanks for the report!

There's not really anything we can do about that I'm afraid :/ many blocks cause crashes with the Schematicannon.

We're hopefully that this suggestion will be implementing: Creators-of-Create/Create#2451
