Steps:

basicly just when battleing numerous campaign mobs in order to gain influence

sometimes I can actually freeze in palace and this usually means different things. sometimes I can be punching the target but be unablde to use weapon skills or move around because I have frozen and also I have not engaged the mob. I still have the attack button up.
sometime I'm just pulling the mobs together and I will be unable to enter attack mode and thay pummel me but I can move. but not engage.
and worst time of all sometimes I will freeze with my back to the enemies in my attempt to pull them and my character will freeze in his current motion. will be unable to move turn or have his alter ego's heal because he has not engaged the enemy. this usually results in death.
this issue occurs both with and without allied tags. at various times of the day and in numerous zones.

EDIT :- sometimes the log will I'm dealing damage as you would expect however there will be no character animation and instead of having the switch target option you still have the attack option (even though I'm attacking) the game shows that I am not in combat and therefor unable to use in-combat weapon skills.

I just died again in Beadeaux (S) due to pulling all the mobs turning and engageing however what happened is once I drew my weapons I was unable to move around (aka to move around the target and as the mobs were still come to me thay ended up moveing to my side and rear and since I could not move I died as a result.

this is not due to the bind stun or petrify effects there is no debuff status effect.

is it possible that too many commands in a short time with the lag generated by a large pull being the cause for this? just thinking......

just died again much the same way as the last time...... this is really annoying I do this for 2 reasons 1: to bring beastman stronghold into my nations control for cracking shells AND 2: to farm Sparks. and since I do the WITHOUT allied tag deaths cost XP and so down limit point gains since I have to recover the lost XP first. this is really annoying and I really hope it's fixed soon before I get too frustrated with this.
