Hi! We can definitely do that! We have the ability to trace the original items and return them, as long as they were claimed. Theft/griefing in unclaimed land is allowed, so we won't return items lost due to this.
In cases of major griefing, we can rollback the land so that it's back to how it was originally. In minor griefing, we can help you repair or fix up your builds if you want.
If any of your claimed builds were griefed or had things stolen from them, let staff know :D
