I'm putting the blame entirely on partner for this one (which he accepts), but which call was the worst?
I think the worst call was agreeing to play 2D as showing 8 playing tricks in a single suited hand or 16-22 3 suited, especially the 3-suited bit.
Essentially it amounts to opening 2N with a 16-22 3-suited, in the sense that very little information has been transacted until opener responds 2N. Now people who use 2N as a flat hand usually restrict it to a 3-point range, sometimes even just 2 points. The problem starting to exchange info at the 2N level is that there isn't much space, and you still have quite a lot of info to transact. That's why people use narrow ranges for the 2N call after 2D.
So what happened? South, who still might have a 0-count, gets no opportunity below the 4-level to show preference to your suit, which might be just a 16-count and with a singleton rather than a void. As it happens, he's got a 7 count with a useful Ace and 4 card support, and a really nice fit. But is he really strong enough to do anything other than bid your suit, when you might be a 4441 16 count (or given that you considered 5530 as 3-suiter, maybe you use this with 5431 too)? I find no fault in South's call, he was forced into it by a system.
North, with his 2 loser hand, apparently didn't find it worth encouraging above the 4-level, when for all he knows your parther, for systemic reasons, could have only 3-card support and probably about 0-12. I think, with a 2 loser hand, I might just have made one more try, because likely partner isn't a 0-count, there are 18 points out after all.
If I had a normal Acol 2C bid available on this hand, I think I'd have bid it. Though bidding over 2C often doesn't go very well either, it is OK on this occasion.
