Bug with characters hidden behind objects

https://imgur.com/a/Z6cYk

You can see the outlines of the legs of the mercenary priest, but the head of the mercenary rogue is invisible (the two chars on the left side)

You can see the outlines of the left arm of the main char (middle) and the outline of the right leg of the mercenary fighter (right behind him).

With left and right I mean my point of view, not from the characters point of view.

Especially the missing head of the rogue looks strange to me.

suggestion:

Maybe it would look better if you can see the outlines of each individual char, not just the outline of all chars together.
