I’m glad the enhancements pass is going through a Lamannia alpha first. Something like this is capable of breaking a game if it’s too buggy.
You can read the forum post here but the general idea of it is that if in the future you reincarnate and you lose your epic destiny experience submit a ticket and eventually it will be fixed. If you lost it in the past, submit a ticket and it will eventually be fixed as well.
In either case your help ticket might go into a “researching” queue while the GMs look into it.
I’m glad they have an official way of dealing with this. I’m sure many people are tired of the “this is a known issue” message with the closing of the ticket.
