Yep happened to me. Standing up from crouch while leaning Q,E throw away my SKS.

I'm not sure if i understand your suggestion. It's already possible to tear shirts/hoodies into rags. Rags work like bandages.

Use a splint or a morphine and try it again. Even if you don't have a 'fracture' notifier you could have a broken arm.

Even if you don't have a broken arm the sway is way to high in my opinion and i consider this is a bug!

This was posted several times before but please make such posts private. We don't need to show more people how to do it.

There is no school building in DayZ. It is a office building but everyone call it school building for some reason.

The dev's already fixed it and it will be patched in the next update.

This is not a bug. The blurry vision reflect the health of your character. If you have a blurry vision you are not at full health. The actual bug is that you can change the blurry vision to normal if you click on preference->video.

Set your object quality settings on high or very high to resolve this. Same bug happen to me with low settings.

Are you sure you are doing it right ?
To chop down a tree you should stand in front of a tree with you axe equipped in you hands. Switch to first person and than if you use the action menu (scroll mouse) a chop down tree option should appear. You have to use the "f" key or pressing the middel mouse button. Your character should now start a chopping animation. After pressing the key several times the tree should fall and firewood appears on the ground or in your inventory.

Same for worms. First person with shovel equipped, aim on the ground (only some ground textures work, make sure you are in a forrest) and press f.

You should also switch to first person if you want to drink from a pond.

You need a knife in your hands and then use the action menu to gather the meat.
It's not a bug you only don't know how it works.

The issue seems to be resolved. I have no crashes since the 0.46 update.
This Issue can be closed.

You can drag an item in the bag or place an attachment on the gun, and the items / weapon attachments will appear. You can also spraypaint the weapon and the attachements will appear.

This issue is fixed in experimental 0.45.12499.
If you now drop an item which is in your hotbar the icon will disappear correctly.

BUT if you put an item from your hotbar in your hands and throw it away, then there will be still a "bugged" grey icon.
