[When you buy a TB you are paying for the TB code not just the tag, so if it goes missing could you just make another using a photo of it and laminate it with the code number? Can anybody tell me if this is allowed.]
This is VERY much allowed. Resurrect all your lost bugs by the method you describe or you can get "Travel Shields" or custom dog tags from GxProxy.com. A bug or coin tracking number is yours for YOUR life, not the bugs. If it 'died' somewhere in it's travels, then breathe new life into it. Be sure to post a new picture on the page and you should change the description and give it another mission. Let's all keep those bugs crawling from cache to cache!!!
