This is an attempt at trying to prevent a weird technical issue that sometimes stops the scene / prevents the UI buttons to happen at some point on cowgirl position.
It seems to affect some of you, but I couldn't reproduce. So I could only hope the slight modification done here will solve it.
If this bug has never happened to you, then you have no need to re-download.
UI buttons should always appear after a while - if buttons don't appear anymore (wait at least 20 seconds), then you've got the bug. The scene should restlessly offer you options!
Reset the scene if it still occurs (as it seems to be a random bug, it could be better the next time) - you have my apologies if it's the case! I'll appreciate your feedback in the Discussion tab.
I've also made a button allowing to change the position appear right from the end the 1st cowgirl animation: that way if it stops at the end of it, you could still jump to another position.
Edit: root cause has been found. The issue occurred only with a beta version of Timeline 5. It has been fixed in the latest Timeline version: make sure you have it!
