    I'm trying to remove a region through WorldGuard's API, and when I use the code below, I get the error message about concurrent exceptions.

    here's my code:

    Thanks for the help,
    AhellHound

    Also, I tried to find a removeRegion in RegionManager, but I couldn't find it in javadocs

    'Cannot make a static reference to a non-static method'
    Just saying RegionManager calls the region manager statically, hence the issue. You need to run the method off an INSTANCE of RegionManager. Try doing it with getWorldGuard().getRegionManager() instead of RegionManager

    Here's the error:
    Code:
    org.bukkit.event.EventException
...
Caused by: java.util.ConcurrentModificationException
    I can't seem to find any good examples on Google.

    ConvurrentModificationException means multiple things are trying to change something at the same time which does not work.
    I'm not good enough to say specifically which it is, so all I can suggest is trial and error.

    Hmm, I've had little luck so far, if anyone else can bring in their input, that'd be awesome, thanks!

    Well my plugin may cease production, as I've tried to also send the /region remove command through console (and I tried to use getPlayer to seem like a player is sending it) with no luck.
