So my opponent using Wood Elves attempted to block my player with his Treeman. He rolled a 1 for Take Root and chose not to re -roll it. He then proceeded to roll the block dice which resulted in attacker down and both down. He chose both down. In the following turn he was able to stand the Treeman up, however take root was no longer in effect and he was able to move freely again.
I presume this is a bug?
