Since people don't check the logs.
There was two minimap/login wipes. One at 1.3.0.0, and then one last night VERY late (Aug 19th) on version 1.3.0.4. I had to address a bad unique ID create. This in turn pretty much destroyed your maps and login again. This is not the same laptop issue people have been getting where maps randomly wipe.
From 1.3.0.4 to 1.3.0.5 (If you had 1.3.0.4) the maps should of stayed, judging by some people whom have been around during the updates, it should be working fine.
