Ugh, Im sorry to not help you, Im asking help from you... , Could you give the tutorials link for me because the dispenser would be useful for my map...
Well, just by following logic, a dispenser that auto respawns will never die, and whatever way you are using to make it autorespawn will most likely make in unable to sap. Sorry to be unhelpful, but I doubt there is a way to do it.
There should be a way to spawn regular dispensers automatically (the way it's done in tr_walkway) and these sure are sapable, but how exactly he did that I've no idea.
Update... It appears I cannot sap any dispensers... respawning or not. I can sap sentries but not dispensers.. I am placing them as obj_dispenser. I am sure I am doing something simple and probably stupid....
