Version 6.03 with XA2/XS2 support is now available on check for updates. 

Also see forum topic for feature highlights.

In previous versions, there was a problem with copying arrays that were referencing themselves, the copy worked until the Qcode expression was checked. 

Solved in version 6.02 (the version also introduce a new keyword, This)

I took the liberty of editing the topic title to make it a suggestion. 

You can (in 6.03), the drawback will be that the HS Expansion bus will have to be limited to classic CAN 250 kbps. This means you won't have the same benefit in bus utilization as you could have with only XC4x expansions. 

Thanks. I managed to reproduce it, added another FGO to the level the channel was propagated to, and changed calculation order.
