If you have unit A -> B -> C and A shoots at C, unless there is some kind of elevation issue, A gets a cover save because of shooting through B. So the tyrannofex should have had a 3+ cover save
That's debatable. You are in cover, correct. In the same way
as if behind terrain. Note that the rule doesn't say you get a
cover save. So we got the terrain rules and read. There it says you need to be 25% obscured to get a cover save.
In some areas they play it as you need to be 25% obscured by intervening models (just like behind terrain). You should always check this with your opponent before the game.
