Sorry if this is a bad explanation but this is what happened to me.
I forgot why i relogged but after doing so (EU PVP J4 server if that helps) all my discoveries and skills were gone/unlearned.
But my stats and current skillpoints didn't. I had 1 unassigned skillpoint left that i didn't use, that one is still available but all the others are gone while i lost all my skills.
And i can't relearn any of them. The weird thing is that i can see the stuff in my inventory under crafting, but i can't actually craft anything either (probably bcs i supposedly haven't learned it)
No matter how many times i click them nothing learns or crafts atm, which is kinda annoying to progress right now.
