If I "upgrade" the level of an cartographer to apprentice,
something weird happens: I can't interact with anything, no entity moves and i can't save the world.
I tried every mod in my modpack and the mod that coursed this was TheBiomeOverhaul.
Strangely the log is just empty...

Here's a video that shows the bug:

I can't think why that would happen...

What other mods are you using?

I tested it without all other mods, exept fabric-api and it crashed, without TheBiomeOverhaul it worked.

Someone said it could be to do with the maps they trade

Could you see if it could be because of the treasure maps? (by getting a map out of the creative inventory)

I'll look into this

Confirmed this is a bug

Nothing appears to apear in the log about this

This really could be it... I found out that he wants to trade an Ocean Explorer Map...
Maybe MC has some problems with it becouse of the new biomes...
I don't think this can be fixed :(

I think I found something

There appears to be an infinite loop with sampling biomes

It didn't freeze this time

@Motschen I changed how oceans generate ... 😄

It was freezing because of how long it's taking to locate the structure: the entire main thread is being devoted to locating the structure

It works now! Thanks for finding this bug!

The game froze for about 40 seconds finding the woodland mansion, and 2 finding the monument

Will upload a new version soon hopefully

Thanks! Keep up the good work! :D

Do note the game will freeze for a few seconds still, howerver this should no longer be indefinite :)
