Hey!
I'm currently making a huge modpack to improve Minecraft (and make my computer cry i guess).
But I'm now not really able to generate world because it would just be stuck at around 0-10% every time I'm starting to generate a world.
So I of course looked into the logs and an error that happened very often was: [Server thread/ERROR]: No key memories in MapLike[{}]
I'm still not sure if that's the cause, but it's a theory from me.
So I searched for the issue and there were only 2 completely matching results,
one from the Forge Forums (this website)
and the Aternos Forums
Sadly the topic has been closed on both sites without really helping me.
Quick rundown to speed up the process:
Are all mods up to date? - Yes, they are.
Which minecraft version are you using? - Minecraft 1.16.5 (FML)
Which version of the Forge Modloader are you using? - Forge 36.2.34
