Feb 2016: Exchanges not made in event tree sequences 
Some exchanges may not be done if a House Events, that triggers the exchange, is not included in the Fault Trees used as input to a Function Event. 
This problem only occurs if you "manually" set a House Event to true to trigger the exchange. If the House Event is set to true in a BC Set, there is no problem. 
Fixed in 3.2.7
