Hello I got a problem as grid centered over one of the subtools I worked with which I haven’t noticed and now I cant use symmetry for further modeling.

Here is how it looks, as you see I was working with symmetry on on the main “mannequin” model, but when I got to the boot the grid moved and now symmetry is all over the place. Additionally I can’t move all the subtools to the object as then any base mesh I import from 3d max will be off. Is there a solution? I couldn’t find it by searching the internet, but I applogise if it was already resolved.
