Reworked the script that determines whether a character is too busy to talk. This will prevent bugs like Minthara's dialogue not triggering at Moonrise Towers after you rescue her, and knock-on effects as a result of this, like not being able to rest or fast travel.
This issue was supposed to have been fixed with Patch 7. However, if you're still experiencing this issue on PC, it suggests that Larian has not fully resolved it yet. Otherwise, you'll need to wait until the patch rolls out on consoles in October.
