Q: Do Old... Properties work with STL and RTD these days?

Reading a tutorial from pre Vassal v3.3, is this statement still correct, I wonder (I don’t think it is my experience)…

IMPORTANT WARNING: In other tutorials or forums you might suggested to use values named OldMap, OldZone or any other variable started with “Old”! I insist you do NOT do that!

Here’s why: 1) these variables are valid only when you drag pieces by mouse, they do not work when you move piece via command such as SendToLocation and ReturnToDeck; 2) using the Dynamic Property “Counted” is the more error-proof method.

You are correct Mark, that comment is obsolete. All traits that move a piece now set the Old… properties.
