Trashing Hovel with Farmland did not gain a card

[CoWm4n]

Hi,
I trashed a Hovel from my hand after buying a Farmland.
However, I was not able to choose a card. (should be one with cost of 3)

probably because the reaction of trashing the hovel, was triggered by the hovel, you could trash the hovel because you bought a vicory card (farmland), and after that you probably could trash an other card because of the farmland.
