IC2 Thermal Centrifuge turned to machine block even it is removed by electric wrench

[Rotomegax The Cube Builder]

Today I use electric wrench to remove the thermal centrifuge to my new base. However it turned to machine block, I read on wiki that this situation cannot appeared with electric wrench. Making another thermal centrifuge is easy but I hope that somebody can find the reason to fix it

It says on wiki what's wrong maybe you have to read it again or read the wrong one.

Did you switch the electrical wrench to Lossless Mode first?
