Please update this plugin to work with 1.16.5. Current issue seems to be that it tries to merge old maps with new maps that are created.

Does by merging you are refering to this issue #86 ? The plugin works in 1.16, the issue of 86# is mainly caused because bukkit is slow to update the idcount.dat file that is used by the game to keep track of the last map id generated

The problem is that we cannot create any new maps larger than 1 map without this happening. This only started happening for us when we moved from 1.16.4 to 1.16.5.

Can confirm that after updating to 1.16.5, the plugin no longer allows us to /maptool list to look at previously created maps. sure we can make new ones but are unable to rename them. Here is the error log

I was pretty sure that we stopped using REGISTRY with the 4.0-pre2, @AmauryCarrade
@0xicl33n Can you check if you are using the 4.0 and not the 4.0 pre1 or 4.0 pre2 ?

Can't reproduce this issue, I'm running on 1.16.5 and on the last spigot build. Does vanilla maps have broken ?

/maptool list does not work but /maptool explore does. downloaded from the latest release on git just now. can close this since explore works in place of list

It was related to our database just being messed up. We wiped everything entirely and it began working fine.
