All of the shapes advance twice on the first generation, rather than only once.

Seems to be triggered when all live cells die. (In the quote it happens on G2 instead of G1 because of the rule change)
I like making rules

One more bug: Drawing state 1 draws state 5 on certain points, while also drawing state 1 two cells to the left. For the previous patterns, at least, this seems to occur on all cells with coordinates (1+16m,3+16n), where m and n are both integers.
