I was following along with creating the lifts and got the first move sequence to work. I copied the lift and started working on the second lift when Zak showed us how to create a subsequence and name it (UpperLift). I didn't select everything and ended up with a subsequence that only had a few of the nodes and couldn't figure out how to undo it, Ctrl+Z apparently isn't an option. I also searched the UDN and found that you could only delete a sequence by selecting it and hitting the delete key. I find that very bassackwards, since now you have to recreate every node and connection that was in that subsequence instead of just undoing the sequence and having everything go back to the way it was before with the nodes and connections not being a named sequence.
So now since it was deleted I decided to just delete the entire sequence select the lift again and start over, the lift now is no longer interp actor 0 when I select it, it's now interp actor 2 when it used to be interp actor 0. I thought the interp actors only updated when you created a new one or a copy of another one, like when we copied the lift inside kismet it was now interp actor 1.
Anyway, since it was now interp actor 2, I said well I'll just delete both lifts and start over from the beginning (I'm glad this wasn't an intricate sequence). I created a new lift and went to start a new kismet sequence and it's now interp actor 3!!! What gives? I deleted both lifts and kismet sequences and there's now only one interp actor in the scene shouldn't it be 0 again? Maybe it would be better if I could provide my own interp actor naming convention, if that's possible.
So in short my 2 main issues are not being able to undo subsequences without having to start the entire sequence over and the iterp actors naming problem.
