Drainage and Utilities - Place Lateral causes drawing to crash - what might be causing this?

I have a water line that I am trying to place hydrants off using the "place lateral command". I was able to successfully place a few then the program crashed when placing a lateral and I have not been able to place anymore without the program crashing.

I have since created new drawings and have found the same problem to occur.

For the node feature definition, I am using a fire hydrant. For the tap node feature definition, I have it set to "no feature definition", as any other feature definition is not valid for a tap node.

Is there any reason that this may be happening? Any fixes? or is this a known bug?
