just tested this my self unchambered my 5 rounds (i also painted it woo i found black spray paint) and then went to re chamber the ammo and it would only allow 1 ammo have not found an unpainted mosin to test it on. ok so i found an unpainted mosin and tested it. I get the load ammo option on the unpainted mosin and am able to load 5 rounds. I spray painted it black and the Load Ammo option Disappears and chamber ammo is all that is left and it only allows 1 bullet to be loaded.

i can confirm that logging out is causing any spray paint can in inventory to go 0% on logging back in.

opt out of beta builds on steam and you will be able to play untill they can fix the experimental build roll back to 113953

Update so it looks like it is just taking what ever my menu screen is and imposing it over the game for some reason i have let it sit for 5 mins and nothing changes or happens.

To note this is what the menu screen at the start looks like just when I join a server I get that issue with the current experimental build (i was the guest poster)
