Loest is having issues with his hero ability and enchantments, most notably speedstrike. Though its supposed to be removed, it seems to reside in the bottom right hand corner of the screen when you click on him, yet it is not target-able, and the opponent cannot cast another.
EDIT: this has happened to me in 3 games. (every time i try to remove it, i suggest someone takes a moment to attempt a recreation.)
