Troubleshooting

Getting the vertices > 60000 error message?
A lot of users report getting the vertices > 60000 error message, this is as far as I know a Unity bug, I can unfortunately not do anything to fix it.
It might help to turn off Show Unwalkable Nodes, or to turn off Show Graphs altogether.
Getting errors in MonoDevelop where the functions contains default parameter values?
Select: Tools > Preferences > Unity > Debugger and turn off "Build project in MonoDevelop".
