Bug Description

I encountered the following error when creating a region via WorldGuard API: https://pastebin.com/njpTDw8h

The code I used was:

import com.sk89q.worldedit.math.BlockVector3;
import com.sk89q.worldguard.protection.managers.RegionManager;
import com.sk89q.worldguard.protection.regions.ProtectedCuboidRegion;
import com.sk89q.worldguard.protection.regions.ProtectedRegion;

[...]

            BlockVector3 upperLimit = BlockVector3
                    .at(location.getBlockX() + regionRadius, location.getBlockY() + regionRadius,
                            location.getBlockZ() + regionRadius);
            BlockVector3 lowerLimit = BlockVector3
                    .at(location.getBlockX() - regionRadius, location.getBlockY() - regionRadius,
                            location.getBlockZ() - regionRadius);
            regionContainer.addRegion(new ProtectedCuboidRegion(regionName, upperLimit, lowerLimit));
            try {
                regionContainer.saveChanges();
            } catch (Exception e) {
                Bukkit.getLogger().log(Level.SEVERE, "Unable to save region '" + regionName + "'!", e);
            }

Expected Behavior

I expect this error not to occour and the region to be saved.

Reproduction Steps

1. Install WorldGuard and execute the mentioned code. This error does occour sporadically.

Optional WorldGuard-Report

Anything Else?

No response

You shouldn't save the regions yourself. WorldGuard already performs the save process periodically in an async thread. You shouldn't do that in your sync thread. Just add the region to the regionContainer and you're done.
