Mercenary bugs are way too severe.

I am playing with a mercenary and the constant bugs that I am encountering with him are currently ruining the game for me.

My build is simple Shockburst Rounds + Galvanic Shards where i use Shockburst Rounds for unique and yellow mobs after i shock them with Stormcaller Arrow.
The constant bugs that I encounter are as they follow. My characters stops moving on one spot and can attack but can't move in any direction. The way to unbug this is by switching to a box and then all of a sudden i can move.

Targets become untargetable to my attacks. After some combo of Stormcaller Arrow + Shockburst Rounds the target i try to kill becomes untargetable and all my arrows go through it. I have spend going around circles trying to hit mobs for minutes at a time with no effect. The mobs simply became literally immune to any Stormcaller Arrow + Shockburst Rounds attacks and the only way to unbug this is to switch around to my bow do normal attacks or to hit with any of my skills but that doesn't always help out. I can't stress how this bug is ruining my gameplay since i am basically shooting at a target hoping it will get killed just to realize that yet again the skills are no loger working for some reason and then i have to go around trying to unbug this shit re apply shock and kill the target. This happens only on smaller/slim targets and never happens on big bosses/targets with big hit boxes.

these bugs are extremely destructive to the gameplay and although they might happen once per map it is enough to ruin the game for me which already has a ton of frekaing issues.
