At this time we've decided that the fixing the issue with the skill loss bug is going to take too much time. As such we will be taking it back to the test server to do more work and we expect to perform an emergency maintenance in the future. We expect to be bringing up the servers shortly. However, this next part is really, really, really, really important.
The skill loss bug is where a player click too fast when buying multiple levels of the same skill and the system registers skill points being spent before it realizes the skill has reached its maximum level. So if the maximum level you can raise a skill is 4, if you click too quickly, you can end up spending a fifth point before the system realizes you've spent 4 points and the skill can't go any higher.
We had anticipated this bug being fixed, and to restore a sizable number of players who had lost skill points due to this bug, we had given out a game wide free skill reset. As such, when you respend your skill points now, don't be in a rush and take your time. We will be giving out a second free skill reset once we get the bug fixed just in case any players miss this message. We will have a system announcement in game, but I'm sure not all players will see it, or this forum post. Please make sure to spread the message to your friends and guildmates.
