I haven't kept up with TAS stuff lately but apparently they said on the GDQ TAS showcase last night that the OoT ACE setup can't be done with a TAS so they had to have a human runner do it then hand control to TASBot?
@trysdyn might be there's a non-deterministic part involved despite their best efforts? *shrug* Feels like the 5th gen is the place where that'd start being a problem
