Your skill is, of course, not a problem, but neither is the spawning mechanism, I believe. This situation could've been avoided if you stood next to the fence. The real problem, in my opinion, is that the game tells you this only when you lost to a cowgirl a couple of times, and only once, which is easy to miss. That's why I will be working on adding more ways to discover this (like the in-game encyclopedia I mentioned before).
Edit: by the way, I really appreciate time and effort you put into giving the feedback, thank you!
