Does anyone know the travel dynamics of a portal? I have checked the Wiki and the forum for this subject and there is not much information on it.I placed a portal and stepped through it. Observed my location and checked the live map. went back through the portal I had just come out of and was not where I had just left. I was in a totally different location. After noting the location on the live map I went back through the portal I just came out of and was in yet another new location. I returned through the same portal again (curious to see how many locations this would take me) and was in the last place I had been. Now the portals were locked between the last two places I had been. But I was not able to go back to the place I started from.How can I set up a portal system if they are not reliable or how do you make them reliable?Is there information on the portals and the effects of them when traveling?If anyone knows it would help, as I am confused by this not being able to reverse my travel through a portal.
