Infinite Obsidian

Okay what I expected to happen was to go to the nether like I had done before I was using the same portal I had been using the entire time it was a resource saver I had put chiseled nether quartz into the missing spots and this was the third time I had gone then I put the chisled quartz went in and realized that there were two portal the first portal the first one ever in the nether the second one the one I had gone through then was also there but two blocks infront of the other portal though I hadnt made a new on I fear if people find out about this the will duplicate the nether portal ( though the first portal doesent work any more ) and try to get an infininate amount of obisidian seeing as a duplicate working portal is in front of the other.

Im not fudging this this realy happened it is a cool glitch and an easy way to get obsidian but its still a bug.

This ticket is very difficult to comprehend, please exact steps to reproduce.
