This is something that has been going on for a very long time. It happens when 2 NPCs have voice lines and they try to talk over eachother.
Is there something I can do to stop it? I don’t think there is, but how can something like this pass QA on multiple occasions and expansions?
I just finished the Maw intro where it happened again where 2 dialogues run at the same time. It appears that something as straight forward as the wait time between them is set to less than the length of the 1st audio clip.
