There should be more organized loot spawning because it will make everything less messy and all over the place. Instead of having random stuff spawn on the floor it should spawn on a table, bed, or in a drawer/wardrobe you have to click on to open.
In the PD's and other armed force places there should be gun racks and cabinets that can spawn in weapons/ammo instead of it spawning in weird places like under a prisoners bed and stuff like that. Maybe a mini fridge or something that can open with food in it. It makes everything much more realistic and less strange.
Also, instead of random ammo being spawned, if a gun is spawned the ammo for it should be nearby (like on top of something). It makes more sense because I wouldn't expect a room full of 9mm's to only have .380's in it. Most of the time, the ammo is at the place anyways but in a different room on another floor. It's not really that big of a deal but the more little things that are improved the better the game gets.

Another thing that should be fixed is that you should make it so if you want to put something on somebody (like tie someone up) they need to have nothing out first and it should probably take more time to do actions like that. Currently, it is an awesome troll to run up to people and rope them, even if they run away, it usually works depending on how long they stand still. It also causes glitches when people restrain others that have stuff in their hands (it makes holding animations super messed up).

A problem going on with grenades is that when pressing G/holding g to throw them it does not work. It either freezes in the air, stays in your hands, or other inconvenient things that causes you to die. It happened to my friend once or twice with an actual grenade, it happened to me with a grenade, it also works with stun grenades too which I am thankful does not really do much damage.

People randomly getting sick. My friends and I were running from SW airfield back to elektro. He got sick randomly. He did not eat anything like raw meat or sew himself up. All he has done was loot, drink from a well, and run. Then, another friend that joined us later in the journey got sick on the way to elektro about 1-2 hours in. He didn't do much either. I am super confused on why this is happening.

About yesterday I noticed major FPS everywhere. My friends and I were having great FPS last week or so and now it got worse for some reason (we went to multiple servers to see if it would help but it didn't).

One last suggestion would be to have the ability to climb trees and then have the ability to drop down.

Maybe add the small caliber gun called S&W 500, super weak and not powerful.
(kidding, have a nice day).
