When casting multiple Kinetic Fields (which currently is possible with just the level 25 talent which increases Kinetic Field's duration), the fields malfunction when they overlap.

If a unit is inside one field, the second field has no effect on it at all. It can walk through the second field as if it is not there.

However, the second field does affect the target, but acts like an area extension for the first field.

This could probably be fixed by making each field place its own modifier on enemies, instead of all sharing one modifier.
