It's looking like I found the intended solution to Dropship no matter how many times I've been downloading it. I remember that it's not the only level of Crane's to have so many updates. I do understand how frustrating it can be to fix backroutes while sticking to rules (And personal beliefs, for example Classic skills).
I'm not thinking about updating my levels anytime soon, particularly Highland Fling. The absence of the basher really is carving a whole new variety solutions that are fun to watch!
I wonder if this can be done with two blockers...
