Quite lucky as once I got this DR I just tried a few HTRs hoping for some big RL shortenings and it spawned,
but I didn't have much else to check so I would have probably returned to this dr (and its twin) anyway.

I had this DR:

but when I checked it once again it didn't work so I thought I had misscrambled it earlier xD
