Selecting both virtual supply trucks and explicit supply

[Mr Grumpy]

The designers I have spoken to about this in the past have been sure that as soon as you select Explicit supply the scenario uses those supply rules and the fact that VST is also selected is ignored.

I found this in the rules...………..

"Note that when Explicit Supply is in effect, then Supply Sources are retained,
but only for the purpose of determining Isolation. Likewise, Explicit Supply
overrides the Virtual Supply Truck rule."
