Act of Heroism doesn't work

[Legendario3]

Greetings.

The Act of Heroism card is not working correctly, neither in the last version nor in this one: when playing it, the target creature receives the bonus + 2 / + 2 until end of turn, but the ability to block an additional creature is not applied .

I tested with Trueheart Duelist and its corresponding token, and its ability to block an additional creature works, so I think this error is only in Act of Heroism.
