I was wondering, as I was out of the country for most of the summer, if there's been another release of Z3 tiles since Orion's spring release--which was notably without combos (due to a bug in importing/exporting graphics packs in B152), and not set up for using the new enemy tile positions.
I've dug a little bit in the forums, but couldn't find anything, and the search feature, it seems, has been disabled again. :shrug:
