If you've sent your report from your alt and it's reproducible, there's no need to send it again.
Thanks for doing that. It can take a little while for reports to be processed, as the bug queues receive a lot of irreproducible requests, and QA have to manually separate the wheat from the chaff.
I have my hands full with achievement support at the moment, but the next time I have the opportunity to do a bug fixing day (we usually get a brief window between two-week sprints to fix reported bugs, and we just started our next project sprint), I'll see if I can find an actionable JIRA created for your issue.
If I had to guess the problem, Salt in the Wound has a peculiar login check to relocate Kennith between quests that probably doesn't get reset by Nastroth. Since you're limited to one reset, fixing that won't help your particular case so would need further investigation to resolve.
