Yes, it's a complete fail on my part.
I wanted to verify how to conjugate this verb and ended up on a classic website "Le conjugueur".
But you can't use that website anymore without accepting cookies. So I went to the "Le monde" conjugueur but it just didn't show conditional present.
That being said I knew and used many times "je croirais" so I don't know what went through my mind :(
They remembered their old moto for a split second.
