I have been summoned !
Short answer in regards to the corvettes on the reference sheet and the mention of decreased cost of 3 IPP with improved construction:
I simply mention it there as a reminder.
I know it’s not strictly necessary and perhaps the reminder should be removed. My desire was to reassure the players that yes, you can buy a ship with 3IPP even though it seems too cheap.
There are new Canada rules out for GW36 v3. There was a time when clicking on the link on the rules page would take you to the CAW v3 v3.2 old rules, while clicking on the link in the expansion would take you to the new CAW v3 3.3 new rules. I think that’s all sorted now.
As for Ottawa connecting to the SZ; I am not part of HBG so take what I say with a grain of salt; but yes. Ottawa is connected to the Sea Zone, and that’s the way I’ve always played it and seen it played in all our games.
