When someone spawned one chest really fast two times, there was two chests and only the last spawned one was detected by the plugin: the first one was staying there with particles and hologram.

Fixed it by sheduling a task later for chest destruction (it is destroyed just after the last chest spawned).

The lines of /lc help are now registered as a string list in lang.yml. it means you can add lines to it or remove some, if you want.
