Do we have rules changelog anywhere, as errata seems to refer only to current version?
Realized this by comparing my NWK / NWT rulebooks and Living rules:
My NWK rulebook (from 2012) says:
For all Transport and Paradrop missions, the enemy player resolves ADF once for each ground unit that is moving/dropping.
Living rules is changed from "Any ground unit" into form "Any stack"
Couldn't find reference to this change in errata though which threw me off for a moment until I realized that errata refers to latest version of Living Rules.
I'll have to see if I can dig up the notes. There's a partial one in the Next War: Taiwan listing, I believe.
