Hey Perry. Thanks for the note and for reporting this issue. This is actually the intended behavior of the plugin; that “Back to events” link just goes back to the current month, since there is no way for the plugin to know whether the person accessed that by clicking in from a specific grid view month versus being linked directly to the event (how they got there would determine where the “Back” link took them). This might change down the road, and you could probably hack something together in the interim to change this if you absolutely needed to, but there aren’t any plans for such a change in the immediate future.
Sorry I couldn’t offer up more here. If you have any other questions, just holler.
