Bug: AI doesn't buy/deploy mines and obstacles

[edox]

Unfortunately, I think that it might be a real issue.

Just to be sure, I just did another test run. Freshly installed and patched free-version of SPMBT: USA vs USSR 1967, letting the AI do both sides' buying/deploying.

USA (P1) assaults USSR (P2): the USSR AI doesn't buy/deploy a single mine in 10 consequent tries (!).

USA (P1) defends against USSR (P2): the USA AI buys/deploys mines every single game, in 10 consecutive trials.

Added to the dozen or so trials I did earlier, with several nations and different eras, I think chance must be ruled out. Perhaps it's an issue with my system, but it's still happening with a fresh install. It didn't happen until the v16 patch (I did a couple of trials per patch while reinstalling them).
