I was in the Reach when we were loading into Euphrosyne. It was around 7pm GMT yesterday.

After waking up and trying again the game's working again so I suspect the maintenance team have applied a hotfix of some sort. But the fact that this seems to happen every patch now is more than a little on the annoying side.

If any mods are about, go ahead and lock this. Though I'll probably end up with the same issue when the next patch rolls around. ._.
