I've been finding that when I use the change sequence function it is causing a fault that prevents the model from running. When I've done a change sequence to move a block of elements I get the message that "The program has encountered an unrecoverable error. The error number is: 179" when running (specifically when it is at the Compute Forces and Stresses stage). Alternatively depending on how I change the sequence I get the message that there is an error with the material database.

Is there a work around to this?
