I am hoping its something silly but I cannot for the life of me figure out why the hammers just do not hit targets. I do not have video but I have tried this with a pack of 20+ and the same thing will occur.
Same thing happened to me using controller. It just stop working at one point during the campaign, the hammer just wouldn’t target the enemies.
I finally got it working again by going into the settings and switching to “legacy gamepad targeting”.
Hope it helps
