Grief Prevention


AUTOMATICALLY PREVENTS ALL FORMS OF GRIEF, including build/break, theft, spam, fire, spawn camping, lava dumping, chat trolling, advertising and more, so you don't have to undo any damage after the fact. It even teaches players how to use it so you don't have to! No configuration or database required. Stop responding to grief and prevent it instead. Grief Prevention will solve your grief problems without requiring you to manage a roster of trained administrators, juggle 10 different anti-grief plugins, take away cool standard game features, publish a training manual / tutorial for players, or add explanatory signs to your world. You can also choose to integrate PvP elements into build design to finally get a PvP experience befitting a sandbox game about creative building.

Grief Prevention stops grief before it starts automatically without any effort from administrators, and with very little (self service) effort from players. Solve all your grief problems with a single download, no database, and no configuration step.

    Why is it that we can't break itemframes inside of claims, but are able to by unclaiming it? How do I fix that?

  • Avatar of RedZephon9 RedZephon9 Feb 24, 2014 at 00:59 UTC - 0 likes

    Any particular reason that users are randomly having their claim blocks set to negative claim blocks? For example some users had 900 claim blocks and now they have -11000

    Following advice to move to mysql below from my catashrophy with grief prevention destroying my sunday, guess what, mysql is BROKEN in 7.8. Following this: I changed the config.yml to mysql, I added my mysql details, It connected, it generated tables, it added some rows, it DID NOT move over a single claim we have just spent hours re-creating, whats worse than this absolute mess is, even after createing a backup of the entire GP before this move to mysql (as I cannot trust this plugin) moving the data back, its put every single player into minus claims, Reverted from mysql to flat, This has gone from completly fucking shitstorm to even worse. How can I fix this? Did we get a new developer for 7.8 or something?

    @stgram: Go

    Thank you for the responce, It took me hours to diagnose that this happened. Being on a shared node, it turns out it was another user that had incorrectly configured a third party backup plugin that created so much backups it filled the SSD very fast creating the crash, Wiping the player claim data? I lost more than the claims for griefprevention, I even thought about switching to SQL for GriefPrevetnion too, Im so anoyed with myself and my host for not having backups. We are pretty new, but now im stuck without any claim data at all. Im stuck in a terrible position, does anybody have any ideas how to proceed from here?

    @GodsDead: Go

    If you run out of space, every plugin that writes data on shutdown will erase its own data, it is a terrible flaw. This is why I keep backups of essentials, and switched to SQL for GP. The data you need is absolutely lost in its current state.

    That is where "daily" backups come in handy for problems of this sort

    I have a majour problem that I need assistance with ASAP, I have had no problems at all with GP for 11 months or so until today, the server crashed last night due to memory, when I restarted it, GP didn't load any of the claims at all, I can see the data is still there, New claims can be created and a restart saves them, but I need to use the data before this happened. The new claims look like they are following the correct ID number we have 358 or so. Its flat file, and I do have access to MYSQL.

    EDIT: I opened up some of the claim data files all 358 are completely blank, GP has wiped all claim data?
