Some bug?

[Hall.Miksa]

I was playing slark in a game: http://lagabuse.com/stats/game/5341121

After one fight [23:41], my autoattack disappeared. I couldn't attack till rest of the game. I could only use spells. It was really a challenge to play slark caster

Anyway why this happened? Is it some internal New dota map bug?

If you want to see epic trying to kill Rax, watch the replay, especially last 5 mins

I tried to die and revivie, to -unstuck, to buy some orb, to drop items, to use Halberd on me by opponent and nothing helped.
