WORLDGUARD-4161 - Reported by imdennys

If you use a dispenser at the limit of region, lava and water flow in the region. (Like, the dispenser it's outside, but exactly on the first block outside the region. If you face it in region and put lava or water, it flow in region).
That doesn't work with TNT/Mob Spawn Eggs btw. But it works with Fireball too. (doesn't affect because of the region flags, but yeah, it works)
You missed this.
I have a Survival server and i use ProtectionStones (it's based on WorldGuard). Please fix it fast.
