I finally got a GM response of "Sorry, this isn't something we can help with - please submit a bug report". So I did. Hopefully something gets done about this ASAP, cause given how many people have posted about his in various threads, I'm sure a lot more people who don't use the boards are stuck just like we are.
Still stuck on Rank 9-> Rank 10. Maxed out the XP bar for Rank 9 , but didn't advance to 10 and have no tasks that can generate Basic Alchemical Knowledge available so I can do Research again to get unstuck. Been stuck this way since Monday morning.
Any chance this patch is going to unlock Alchemy levelling for those of us who have gotten stuck at 0 xp to next level when we finished the Research Task on the Gateway? I've been stuck at going from 9 to 10 since Monday morning now since there is now no way for me to generate any more Alchemy XP.
The same thing happened to me today going from 9 to 10 on the Gateway. I've reported it in-game. Hopefully this gets resolved quickly. The lesson learned here seems to be don't finish Research tasks on the Gateway for the moment.
