It happens to me while I was doing the test, I was heading to lx and it appeared to me "OMG! reload" so I realoaded the game and when it came back I was in a different place, not the one I was before reloading it.
I wouldn't worry too much about it, things get a little hectic during test days, (especially early on) and sometimes we reset stuff or things get shuffled around. These kinds of things shouldn't happen very often when we finally go live, and when they do it shouldn't lead to your location changing every time.
