Honestly, the inventory and weight management was the least of my issues with the game.
They should fix the numerous spots on the map where if you fall in, that's it, it's game over. There's a few in the various marshes next to big bodies of water, with holes in the terrain that you cannot jump out of due to being filled with water and the edges too steep. You cannot walk out of them, can't slide, can't horse, can't even glitch out of, and the only thing you can do is reload or quit the game.
Teleporting enemies is also really annoying. You'll be in the middle of a fight when an enemy just disappears and reappears within a single frame on another part of the map. Easily reproducible with bilge hags and no, they are not going under the water like normal. They just instantly teleport with no animation. I think it's a bug with their submerging ability though I've seen it happen with wolves and bears too.
Good on them for fixing bugged quests though, that was getting annoying. Go here. Nothing happens, nothing triggers. Talk to <X>, they're not there. Finish quest, suddenly it's a completely different time of day a second later. Talk to person, they become a different NPC, have broken dialog, and then it places you in a random nearby location when the dialog ends and delete that new spawned NPC a few seconds later.
Hopefully the new movement system lets you move more freely in combat so you don't have to spam light dodge to get everywhere and stops you from sheathing a weapon automatically in the middle of a fight so you start attacking with fists unknowingly.
Game is really buggy sometimes.
