Been meaning to report this bug for some time but I keep forgetting to.
When you are inside a town region upon being notified "Welcome to [town]" or rather, skills do not work on creepers; fireballs fly through them, pulse does not damage them, trying to bolt them returns "Target cannot be damaged" or something similar. If you are killing a creeper and half-way through hitting them, the skills also stop working. Left-click spamming still damages them however.
As soon as you leave the region and the "You are leaving [town]" message appears, you regain the ability to damage them.
As you are able to snipe creepers that are inside the town region from outside the town region with fireballs, thus this leads me to believe it has something to do with region permissions. (However, this problem persists even when you are standing on your own town turf so don't get any funny ideas.)
