During the tutorial at devnology there were many Windows machines where the editor would give multiple definitions errors on each definition. I am able to reproduce this in a virtual machine with Windows XP, for each definition the error log view shows:

Term is not associated with an AST node, cannot report feedback message: Define([],"eventEdit",[Arg("e",SimpleSort("Event"))],None,TemplateBody([])) - Template with signature eventEdit(Event) is defined multiple times.

java.lang.RuntimeException: Term is not associated with an AST node, cannot report feedback message: Define([],"eventEdit",[Arg("e",SimpleSort("Event"))],None,TemplateBody([])) - Template with signature eventEdit(Event) is defined multiple times.
