Hmm odd. The stamina hitting zero certainly should have stopped sprint. It appears I have lost a bit of blueprint somewhere along the way. Will have that rectified asap (an hour or so). As for the stamina filling up endlessly, I dunno how I missed that XD Already fixed though (3 second fix haha) so that will be pushed int he update with the other stuff.
Inventory excluding realtime… thats a new thing. I had that fixed in 4.8, but it appears to have popped back up now in 4.9. I’ll have that sorted - I was trying to avoid putting any real customisations in the player blueprint, but in order to add some of the things people want me to add I’m going to have to add a bit here and there, so that’s an easy fix anyways.
Basic container - are you talking about things like Chests? An inventory ‘bag’ sort of thing that players can deposit things into?
Thanks for the awesome work 
keep up the feedback please! It really helps!
