Thank you very much!

Have been playing 0.59 between christmas and new year with a buddy on my internet connection. It worked absolutely flawless, no problems at all.

I have had this as well. I don't know wether it's a bug or if the fuel tank leaks.

There is a temporary fix for it:

1. Look through scope on gun --> glitched, white textures
2. Put scope in in inventory
3. Put gun on your back
4. Take scope in your handy, raise it via "backspace" button
5. Press right mouse button for several times
6. Eventually the white texture glitch disappears
7. Put scope on gun and use it as usual. Fixed!

This procedure fixes the bug client wise, not the gun/scope itself. When I gave my fixed scoped Ak74 to my buddy, he had to go through the procedure before using it correctly.
After relog the procedure is to be done again.

I had the same glitch as well.
I throw a barrel with "g" and it stays glitched in my hands.
When i press the "g" button again, the barrel disappears.
After relog (maybe after server restart - I don't know exactly) the barrel is at the place where I pressed "g" for the first time. The barrel is perfectly functional then and can be accessed as usual.
I've had this situation twice already.

It definitely does work with newUi.

I had this alot when double carrying guns so far.
Yesterday,I had it several times carrying only one primary weapon. It was a crouched sliding animation every time.
Unfortunately, I don't know how to reproduce this bug.

I can confirm this.

I can confirm that the map is not showing up. When choosing the map from the hotbar, I get texture glitches, which resolves after a few seconds and that's it.

Today I had a scoped Blaze and my secondary was an Mp5.
I don't know how it really works but changing guns somehow changes the font color of your zeroing.
By switching from Mp5 to the Blaze I could change the font color to white and I could read zeroing numbers perfectly then.

I saw it today.
