When working at ci=1 on 562, wiggle all with bands caused the backbone to pass entirely through itself - normally I can only make that happen by setting ci to 0. During the same wiggle the backbone passed entirely through the shadow as well.

Before wiggle, no clashes: http://fold.it/portal/files/chatimg/irc_341210_1337878209.png
During wiggle, one section of backbone inside another: http://fold.it/portal/files/chatimg/irc_341210_1337878243.png
During wiggle, backbone inside shadow: http://fold.it/portal/files/chatimg/irc_341210_1337878294.png

ci=1 throughout the wiggle. Result is reproducible using solution shared in group as "clash importance fail".
