I would use the node finder in SignalTap to make sure that the nodes that you tap are still there after the change. If you are using post-fit node names these may change when you change the width of the data path. For instance, if you made the width of the FIR output narrower, then your SignalTap instance may have references to non-existing nodes. Furthermore, I would expect a critical warning by the end of the map report related to signaltap that could shed more light on what has gone wrong.
