Matt Arnold posted this in another thread:
"Yeah, if it happens in any parks that ship with the game, people should report them in the 3d thread with the full movement details, as well as which exact park you are playing in.
If it happens with a park from a community modder, you should mention it to them. Often it can be a case where they specify the grid ever so slightly off from where the actual fence shows in 3d, and so it's something they may need to correct. There might still be corner cases with some parks, but it's best to check with the modder first."
