OMG, great tip, JPD. Thank you. Super maddening bug. I have a really elaborate preset I've been working on all day, and after I deleted some blocks and re-mapped some Stomps none of my (dozen or so) remaining blocks (that I didn't touch) respect snapshot bypass anymore. Copy-Clear-Paste each block seems to get it back, but then I need to remap all 8 snapshot and dozen or more blocks. Very much looking forward to 1.2.1.
