Was told by another ls member it happened to them too, in a different zone. GM couldn't explain it and submitted a bug report for me. Maybe the reason for the maint - or one reason, at least.
I don't know about anyone else but i went to edit a macro last night and all the names in my macro list were to the default names (i.e. book2 was named smn and now it says book2 again without changing it)
i didn't check it today, kinda forgot about it until reading this post.
