Upgrading Harpies isn't the worst move. Many people upgrade them on 111 for faster map clearing speed. In general, happiness isn't about dragons or portals. There are also Griffin Conservatories, Dragon Fly Hives, other external dwellings, artifacts, Pandoras. For example, 4 external dwellings of Troglodytes and something else with a portal will provide decent cannon fodder. Plus, a successful hero level-up or buying the right one could also have made a difference. Tons of examples can be thought of.
You can think up anything you want, any number of examples, but in reality none of this was visible, only a Dragon Fly Hive for the Horde of Lizardmen, Harpies still needed to be built, the Tactician didn't come. The party couldn't be won further just by force of imagining goodies.
But in this particular layout after the block, everything was within normal limits.
Except maybe the tempo.
