I noticed something a little interesting, when one TG instance is eroding, another TG instance will have a un-editable (super slow/frozen) plugin instance. Are they somehow tied to the same resources? Everything else in the second TG instance works besides the DK:CE plugin while the other is eroding. The window will open, but changing anything causes the plugin itself to freeze (not a not responding freeze though), for example clicking a checkbox will highlight the checkbox, but it wouldn't "check" until the erosion in the other TG instance was finished.
Edit: Doing some extra testing, it seems I can get "one" change out of the second instance of the plugin before it than locks up until the other is done processing.
