[Bug] Ataque travado

[VNSlayer]

Does anybody know how to fix this issue? Im facing the same. Whenever the field is amplified by Freezing magic circle (or whatever else I couldn't remember exactly, but that's the buff from enhancement skill) MU helper (mobile) lock target on my self, it only change to other target when the frozen field disapears
I have attached the screenshot 

   

Thank you
