So i found a bug! D:
The Stamina fills up endlessly… If i would wait like 5 minutes i had enough stamina to sprint threw my entire 5km² island XD
Im Using time 1440 for 24 minutes
End yes Stamina at this point does nothing. If the player has 0 he still can sprint jump and walk like hell 
The Inventory does not exclude realtime. Wich means i fire the gun when i have the menu open… I can easily wich that but thats a bug.
Try this: Take an item open the inventory and press drop 10 times. Endless Water bottles
What about a basic container for items! Wich can easily be placed in a AIm Actor at anytime!
