Curious enough, I just realized that I was in fact running the old version (non Steam). I accidentally picked the wrong icon on my start menu. :oops: I didn't noticed because they both use the same save files.

To answer my own question on changing the versions, I only saw problems with a few trees ...

My Steam Game is running version 0.9.8.

It hasn't updated to anything higher.

I noticed I can set the 0.12.29 or even 0.12.30 in the "opt in for Beta" Part. Is this what we have to do?

Also, Will my 0.9.8 game work on 0.12.30?

I'll just run it. What's the worst that can happen.
