So, a friend told me that someone used a coaster I made and claimed it as their own. For those who are wondering, I made that Flying Dutchman and he got it from a public download on RCTgo which can be found here http://rctgo.com/downloads/view/12599 same thing with the other rides. The Old Mill is available for public download as well http://rctgo.com/downloads/view/12794 Seriously man, if you want to use other people's work for yourself you need to ask them at the very least.
