Kicked to character select with 0/2 char slots

This just happened to me not long ago, I was doing the tournament in Gunnar's Hold and I ported back to town at the beginning of a round (trying to get Zho -_-), as I did however I was immediately thrown back to the character select screen with two character slots, both of which were empty. The weird thing was it threw me straight into the campaign select part, but only Proph and PvP was available as an option.

Is this a known bug? It fixed itself by logging in and out but it was scary.

was happening to me constantly yesterday
seems ok now

I have experienced this multiple times myself, although it's been a while now. Never really figured out what caused it, as restarting gw fixed it. It did always happen when map traveling.

happened to me at least once as well, last time was during the observe dcing glitch

I found that sometimes when I'm mapping to places, if I click a few too many times that happens to me. It's a common issue, so don't worry too much about it. All you can do is log out, log back in. Fixes the problem every time for me.
