[PROBLEM]New Mounts Can't Attack

Hello guys
I have a big problem
I use Vanilla Project rev55170, all works fine but the newest mounts as Unicorn, Dragor, Leopard, cannot attack
Here are the mounts :

With these mounts i'm not able to attack...
But with the others i can attack! I mean all the other mounts!
This problem happens only with the previous mounts
I really don't know if it is a problem with the game file, or with the client (launcher i mean)
I really don't understand why they can't attack :(
Can you help me fixing this problem please?
File server is Maxmi # Blackforce 3.6 (Vanilla Project 55170) And the Client is the same of Server File!

I'll wait answers, sorry for my bad english, i'll hope you could help me.
Thanks a lot!
Best regards.

If you aren't able to attack, then the problem is in your Binary.
Look for an difference file, or if you work with Gamesource just change it, there many users who had the same probleme.
