Craft parts explode in slow time compression

When using time compression below 1X some parts explode. Going above x1 time compression works fine.

NOTE: this has only happened to me with this craft. I can't seem to find which part in particular (if any) is causing the problem but it is worth mentioning.

Load the DesignerCraft associated with this bug report and then enter flight. Enter slow motion. The craft will explode on the launch pad.
