Monstrosity - Unable to perform that weaponskill issue

I dont know if this is the right section but as i see more Monstrosity problems are stated here so i throw this one up.

I am a sweet lil' bunny in Monstrosity and every time i try to 'weaponskill' (any of em) when i just engaged a monster, i get im unable to use that weaponskill (or something alike). This happens either 1 time, or up to 3 times in a row making me pretty much not 'oneshot' anything. I also have it on mandragora so i assume every other pet has it too. My bf has it on his lizard as well. But unable to ws also happens occasionally during some point in a battle. Even when an enemy is 50% and i hit it for like 20 sec. i still can get this message.

I hope this is just an easy fixable bug =) i hope there aint a thread about it already >..>'

It could be that you're moving when you try to WS... i noticed that when I was playing as a monster, and the only time it did it for me was when I was moving when weaponskilling.
