Hi Demonhunter1107, it’s good to hear from you 
Thank you for your feedback regarding the inventory changes. I understand how after playing for a long time this could disrupt your gameplay flow while you adjust your gameplay style. I will pass this onto the team.
I hope the new inventory space and piles will help combat against glitching and freezing for you. Please do let me know if you notice any difference
Also, you probably already spotted it, but in case not the latest patch notes and details can be found here: [Console] Update 2104 Notes
