Arghh... BG1NPC adds the possibility of keeping both Edwin and Dynaheir, but that new dialog option was not cleaning up the Rescue/Kill Dynaheir quests in BGEE. I'd added a variable to add the needed EraseJournalEntry() commands on BGEE and then somehow moved the variable declaration statement to be *after* x#dynaquest.d was compiled. *doh!* 
I've uploaded a fix to GitHub. BWS appears to be grabbing the latest "work-in-progress" from GitHub, since your log notes version 20150320 (the official v21 release is dated 20150210). The fix is in the current "work-in-progress" at https://github.com/A...hive/master.zip
