Invisible Master bug

[WorldShift]

I was playing Dunetown base with Hadouken. At the beginning of the game, as soon as the map loaded, in the chat area it said "DESYNC DETECTED!". I was still playing with Hadouken because I could see his creatures moving and he could see mine moving. Well right before the creature cages part my Master (hero) got stuck on my screen and couldn't move even though nothing was blocking him. Hadouken said that he could see my Master moving. We did the creature cage part and then I moved my Hellfire up to the artifact because my Master was stuck. When the artifact was revealed I selected my Master and then right-clicked the artifact like usual. My Master still appeared to be stuck but I could see the bar appear over the artifact as though the object was busy. From my view, Hadouken's creatures and his master were still behind my Hellfire by the time this bar appeared over the artifact. He said that his Master was using the artifact though. I am not sure what was happening but I here is a screenshot:
