All the time.

They can do anything they want, or at least try to. That's part of the point, as far as I'm concerned.

If you have, did they respond how you expected them to, and did it mess with your plans much?
It doesn't always go as I expect, but that's fine. In fact, that is even what I expect. I tend to plan things in segments with a major choice lying at the end of the segment, so I can plan the next one depending on what they did at the end of the last one. More minor choices get worked in as well, just in other ways.
