Matchpoints, ACBL robot individual

Should I not have been surprised that North passed 2NT in this sequence holding a full 13HCP with 5-card ♣ support? Is it not puzzling that North bid 3NT with this same hand at its first opportunity when South elected to open with 1♦ instead of 1♣? And that if South bid 2 of a suit before bidding 2NT (still promising only 11+ HCP), North raised to 3NT?

Given that North has previously rebid 3♣ in this sequence with ♣Jxxx and an 11-count, it seemed unwise to bid 2 of a suit over 2♣ holding a 3-card suit and risk getting beyond 2NT if North has less than an opener. But I really did not expect North to pass 2NT with more than a minimum for its inverted raise.

Georgi's first post in your link advises that this has been fixed in 3.1. I guess this is in the "not quite" category, like the robot's habit of raising 5 of a minor to 6 after making a non-forcing bid.

Yup.
