*Replacing a fix, but new style != old style*
A fix ID can be used a second time, but only if the style matches the
previous fix. In this case it is assumed you with to reset a fix's
previous fix. In this case it is assumed you want to reset a fix's
parameters. This error may mean you are mistakenly re-using a fix ID
when you do not intend to.

If your simulation is a hybrid model with a mixture of rigid bodies
