So, I found this bug when I was creating a park... I have selected several wooden coaster types (in scenario editor), articulated, normal, and the 6-seater, after everything was saved, I went into the park and started making a coaster, but the only type that showed up was articulated, even though 3 were selected, and that I made sure everything was on the invention list.   No, it didn't happen once for me, I've created several parks all with the same problem. I've only run into it
