\n– The ground scan ignores player-placed blocks; when CoreProtect is available it will also treat historical placements as player-placed.
\n– Use `\/lavacast mark
\n– Marked blocks are stored on disk in `plugins\/AntiLavaCast\/marks` and persist across restarts.
\n– When CoreProtect is enabled and detected, mark storage is disabled and lookups rely on CoreProtect instead.<\/p>\n","protected":false},"excerpt":{"rendered":"
