[AntonPPDS]

The same issue

[pineapplebox]

bump

[thefrostyhalf]

Bump again, has anyone found a reason for this error or workaround?

[suerion]

[thefrostyhalf]

A few things we have found that will cause this error:

• User-created maps
• Chests
• Maybe wheat (still not sure)
• Maybe beds (also not sure)

Wa has already the chests, but it does not work, do replace it, the nbt is already there,

It could be some other things, we found not other solutions.

Hey @thefrostyhalf @pineapplebox @joserobjr @AntonPPDS @siebsie23

our dev had implemented an debug, the block and the cord would be seen

Java2Nukkit-World-Converter-3.2.2-SNAPSHOT-cli.zip

Please, try it with this,

we thougt, the converter, convert not the blocks to the right ones -> barrels to chest, seagrass to water and so on

[suerion]

Oke new debug update

The world conversion has failed

[suerion]

so we had also added the waterlogged debug -> please add this in future in the converter, it would be easier @joserobjr
