I've started a wizard playthrough and came across this issue multiple times. When enemies in the backline not engaged by any allies are attacked, they move towards their attacker, completely ignoring other creatures in the way.
If the path is blocked they move their allies out of the way, sometimes out of AoE spells and more. Here is an example
This is not limited to 1 enemy moved either. Eder can engage 4 enemies but one creature in the back can move all 4 of them out of the way to go for the wizard in the back.
Companions have no trouble blocking each other in the same situation (they try to move around allies), so why is that not the case with the enemies? It's like enemies just don't stick to the floor properly or something.
Anyone else has this issue?
Edit: After some testing, I noticed companions also doing this occasionally. It's like when characters engage something they become attached to that rather than the floor.
