the bug was related to dynamically loading routes, but the true cause was that express allowed duplicate handlers. They were loading routes dynamically correctly, that wasn't a problem, it was that when doing that express let them duplicate routes.
> Multiple callbacks may be given; all are treated equally, and behave just like middleware. The only exception is that these callbacks may invoke next('route') to bypass the remaining route callback(s). This mechanism can be used to perform pre-conditions on a route, then pass control to subsequent routes if there's no reason to proceed with the current route.
