I have logged in. I even tried just now to simply reinstall the game, create a new world and trigger an achievement I don't have that way, but even that doesn't seem to help.
I was aware of those cases, so I've made sure to wait at least 10 minutes to check if it didn't trigger after all, while I had an active connection. Nothing happened however.
I had also run into this issue.
Here's a world download: https://drive.google.com/file/d/1CF9gZZhcgjP7AmWDhOjCsOKgQ7WGq6Nl/view?usp=sharing
Bugged chests can be found at: 787, 95, 1037
I already fixed some chests by breaking the invisible blocks and replacing them.
In addition, this is the log of BDS when the crash occurs
Unfortunately, that also doesn't seem to help.. I've in the meantime also started a thread with mojang support, in the hopes they can help out. Thanks anyway
