Ive been having this problem on my server where in certain areas players act almost as OP's. They can open protected doors, locked chests, interact with blocks they should not be able to interact with. And it has also caused problems with OTCO. Through some detective work i have found out that this is due to Chunks reporting as Air, but it seems entirely random and possibly the same chunks do not always act this way. I cant really confirm it though. I am unable to find any other documentation, complaints, descriptions or fixes other than what is available in threads for Factions, and OTCO. I have no idea if this was caused by me misconfiguring something in the past or installing a buggy plugin, or if a plugin still in use is the cause. I think i have limited the occurance of the buggy chunks but it could be taht users have just migrated to new areas after "strange griefings" These are the plugins that I believe are related to this, but are not necessarily the cause BananaChunk (disabled) Ore to Client Obfuscation (disabled) Lockette (disabled/no longer needed) Factions Spout Have any server admins thoroughly tested this? Has anyone narrowed it down to bukkit or a specific plugin. Are any Devs working on a fix? If this is a Bukkit problem, are the Devs aware of it? Do they have a timeframe for when it could be fixed? Will it be possible to fix for existing maps, or will it be necessary to generate a new map for the above mentioned things to work as intended? nothing? no info available at all?
