This happens when someone gives you a claim and you delete it.

If you have 300 claim blocks, and you get gifted a claim thats 21300 blocks, and your thinking Phwar free claim blocks nice, Lets abandon this claim! Its going to minus those 21300 blocks from your account.

This has happened a few times, and this has always been the case, can you please confirm.

I was just about to post a ticket with this exact same issue, to my knowledge i have never been gifted any claim blocks nor ave i sold or abandon any recently, and i ave -1500. Was going to make my own ticket but as raven has the exact same issue i thought it might be best to post on here about it as are problem could be related.

I hit the max total of claim blocks possible ! 60k is the limit and no i am not getting anymore unless i buy them unless of course it gets shot with a nerf gun

Lucky you will be missed 🙁

Im planning on migrating to the new griefprevention soon, which im sure will cause absolute havock, but I have no choice as name changes are coming Feb 4th and this version does not use  UUIDS, so im saving up all GriefPrevention troubleshooting until then.

If the error still persists, I will set everyone in minus back to 0, There have been countless bugs always with GriefPrevention that set claims to minus numbers, The main cause is what I described earlier, but since people want to get their claim blocks reset they tend to lie and say “It was the plugins fault not mine” so there is no way I can troubleshoot without complete truth from players.

I have requested a “history” feature be put into GriefPrevention so then Its possible for me to see the history of claims, but until then, im reliant on truth!

I will reset minus claim blocks back to 0, but I plan on doing this all on one night when I do the conversion first, im absolutely bricking this and have been putting it off for months.
