[2020] I think the AI pathfinding is not working properly after the last update (Playing SP)

Hi! This sounds like it may be because of the autopilot changes we made intentionally to deal with the new environmental hazards. The autopilot is very cautious around ice spires and tends to stop near them, so some manual steering may now be required in some levels. We're monitoring the feedback, and the prevalence of autopilot use is coming as a bit of a surprise to us; we'll continue keeping an eye on things! If it seems this is not the problem for you, please let us know more about what went wrong :)
