Unleashed, Mage multiplier and Dwarven Armorer were all from after I opened the first research for chapter 16 so your assumption is mostly wrong. I finally got lucky enough to get multiple troop boosters in the MA. I'm usually only lucky enough to get about 1, maybe 2, per week. I also got the Dwarven Armorer in a mystery chest in the spire during the 2 levels I have finished so far. Very happy about how all that played out turned into very disappointed that there is a screwed up glitchConsidering the amount of buildings you call up I assume this is not the case.
ONLY the buildings from the embassies chapters are not working and I assume you did not get all those combat buildings in the past 48h
Scrolls is by far the worst tournament, after that I personally tie both magic dus and crystal as difficult tournaments.
Especially since the elvenar chapter has crystal become an enormous pain in the butt.
Anyway, since they say it will be fixed with "next" update I'm thinking they mean tomorrow morning. I'm just going to wait until tomorrow and see. It still sucks that I burned through as many troops as I did & time instants to make more when it shouldn't have been so bad.
Adding: At least I did get a very pleasant 2nd response from Support
