"My previous house was small."

Vertaling: Mijn vorige huis was klein.

[oldtimer1945]

mijn vroegere huis : is toch hetzelfde of niet ?

[hendrikvanes]

Mijn vroegere huis hoeft niet mijn vorige huis te zijn

[apgdl]

"Mijn vorige huis" and "mijn vorig huis" are both considered correct here, but I don't understand why. According to dutch grammar rules (https://www.duolingo.com/comment/3888221), only the first one should be right. What's going on?

[MentalPinball]

You're right. Have you reported it? Probably it was a bug, I assume.
