Your "additional information" clearly shows you did not understand the first window displayed in the game. This is alpha, for everybody who does not understand what this means, please stop reporting bugs.

Back to topic:
I have experienced that bug as well. Relogging to several servers sometimes brings your old character back (in cases where you're character was reset due to loading problems).

dude, the map is not done yet. deal with it, early alpha

Okay, thanks for the replies, so it seems I just picked very bad Mosins then.

Seems then the "bug report" rather should be concerning the missing weapon condition, not the game mechanic.
