"Die-hard" bug

If you go to
this link, it has a pattern in B3/S23 comprised of long^2 beehives with y=8191.
For some reason, the pattern dies at T=1. Patterns drawn very close to the fuse also disappear on T=1, but patterns far enough away from it evolve normally. A pattern in this sense is a polyplet.
The threshold seems to be 4 or 5, and any patterns within the threshold extend it to the xpos of the new pattern.
(Or maybe I'm hallucinating. Who knows?)

No, you've just found the feature of LifeViewer that cleans up spaceships when they hit the pattern boundary, thus avoiding the weird edge-effect junk that you sometimes get otherwise, bouncing back toward the center and doing things that would never happen on an infinite grid.
The default DELETERANGE is 3. If you add
#C [[ DELETERANGE 1 ]] to that pattern, it will only clear cells that directly touch cells on the edge of the pattern, so the top and bottom will stabilize more or less normally. Or probably a better solution is to add
#C [[ MAXGRIDSIZE 14 ]], so that the edges of the pattern aren't close to the edges of the LifeViewer grid any more.

Wow, that's strange (i'm the poster of this post)
