Yup, M4 and Magnum will be rare after the patch. More civilian weapons like the double barrel shotgun, ruger hunting rifle, sawed off double barrel will be available.
Mosin spawns should still be the same.
Yesterday was playing with Rei7 and he had the desync issues everytime he is logs in near me.
However after throwing away his ammo box, med kit and yellow containers, the 100k desync is gone. Similar to my desync problems, previously I had a medkit in my back pack but threw it away. So far no desync yet.
So if you are having problems activating your quickbar, interacting with your inventory, or don't see anyone moving in your group, there is a good chance one of them is packing containers within a container. Like a bag within a bag. This will be somewhat addressed in the coming patch were you can't put a filled bag into another bag. But no news whether containers (yellow) can still do it.
If you are the only one desyncing, it could be your inventory. As in Rei7's case, after he removed the containers, it helped with his desync issue. This is currently a game breaking bug especially for groups as they can't play together effectively.
100k desync does not have any game indicators (red/yellow chain), other than unable to equip weapons, your inventory does not respond to your right clicks, unable to open doors, interact with loot and people/zombies stuck in one location.
It's a fast way of getting killed if you don't know that you are desync. I make a habit of checking whether my inventory can be accessed or not, just by Tab and right clicking any items. If the item just shows "Receiving." and doesn't do anything, then very likely you are 100k desyncing.
Yeap this true, happened to me and bestdo when he picked up a small protecter case. We thought it was cursed hahaha
