I have a private server where I've spent 3 in-game years slowly building. I wanted to upgrade to 1.21 as well as add in rivers and change some of the settings for BetterRuins. I only care about a 20 chunk area of the world with my main base. I couldn't find an easy/reliable way of deleting everything around my base and regenerating the chunks ... /db prune keeps crashing the instance. So I decided to start a new world and cloned my base into it. Other than some tree-limbs not rotating properly, most everything looks ok. However, I am having an issue with the player data.
I wanted to keep my seraphim and items, so I stopped the instance, and used SQLite to copy the playerdata from the old instance to the new one. Everything is wrong. All of the tools in my hotbar (pick, shovel, axe, etc) were converted to ore chunks and storage bags gone, etc. Seems like the block IDs are wrong. If I copy the 1.20 world and start it locally with 1.21, the remapping seems to be fine and everything carries over. But even copying this updated data results in the same issue.
Is there any way of resolving this short of going into creative and giving myself everything, one item at a time .. setting durability, etc.
Thanks.
