(Note every mod with the word "Letra" in it was made by me, and doesn't effect scripts, or vanilla companions, or even the companion wheel so that's probably not what's causing it.). Also I tried without EDE as a sentry bot, so it isn't that either). Also note that this happens when RoboclawBeta is far from the bottom on the list.
Edit: Apparently it was Small Talk. The work around to this issue, is to turn off the mod, recruit EDE then turn it back on I think.
