I've been the victim of a SDTM more times from hitting the 'Slimer' target to spell G-H-O-S-T than I have from the magna-slings grabbing the ball, whirling it around, then throwing it SDTM. Does it suck, sure, but that's pinball.
I've suffered a SDTM drain on almost any pin I play, some more than others. The ball has to go somewhere, and usually there are only 3 places on a playfield that it can drain. SDTM drains have been plaguing players long before GB hit the scene.
Easiest solution: hit the start button and flip another game.
