[(E)]

A drive that warps space or creates a wormhole of some variety could be misfiring and creating small random holes in space time around the "drive core", if left alone these holes will further damage the containment systems. The repair crew sent in will have to repair or temporarily shut down the drive safely while dodging the emerging rifts and dealing with the new damage they cause. Added complications could ensue if there is additional damage like hull breaches or electronics failures. Other players could be involved to act as look outs for the engineers or to perform urgent repairs on new damage while the engineer repairs the core.
