When you press tab, you see your inventory and if you are hidrated/energized, hungry etc...

But sometimes, when you connect to a server, you can't see your indicators when you open your inventory and you don't know if you are hungry, thirsty etc. you have to connect again to fix it, last time I had to connect 2 times until it got fixed.

If you were energized when you connected to the server, the modifiers show you "high energy" but they are stuck until you reconnect again to the server, if you are hungry after to a time, you wont see it because it's stuck

If you receive damage, your blood indicator doesn't change neither, it seem stuck, and health too.

It happend few times.

Sorry for my english, I hope you understand me
