Attack of the B-Team fails to start world

[Haroldean]

Hello-

I've built an insane world on AOTB but a few months ago it wouldn't let me start my save (The modpack launched fine, but says "Shutting down internal server" after a few seconds)

I thought the problem had to due with villager.dat files and i removed them, but the issue still stands.

Crash report:

I read thru these forums that modpacks can appear on these reports which confirms that that specific pack is the issue, but not sure about where the issue originates in this report

Hope one of y'all gets back to me to make this quarantine less boring

Mapwriter config got borked. Its either the main config file or the waypoints for your minimap.

The borked file can be deleted just fine, although in case of the waypoints, you'll lose all the waypoints on your minimap.

The location of the file you need to delete can be found in the error juuuuust above what you pasted here.

Awesome! Worked once but now the save wont pop up when i launch AOTB - Tried a new world with the same name as the file but the game just crashes now...
