@MVNLA2 I did notice that, but this is a separate thing. So one level, two different self-destructs!

ABS ACB 1-12: right tower starts swaying to the left right after restart (about 1 in 10 restarts on my Android). Most of the time it settles again and stops swaying, but seen it collapse once (taking about 30 secs), causing partial destruction with some 66k.

Had a 0-birder on ABO BDP 4-7. Large tower started swaying, then collapsed. All piggies killed, 133K score. Am playing on Android.
