Weapon level says 0

Same here, when looking at the individual guns in the loadout menu. There is usually a badge above the progression bar & level too, but its missing that too.

okay just realized if you click/go to customize weopon, it does show correctly - although not helpful when trying to compare other weapons. 

Same here , I think it's for everyone , hopping for a quick hotfix , it is indeed annoying !

All of my weapons, aside from the ones currently equipped, were reset to 0. Not just showing 0 on the screen, but actually 0 and all the attachment unlocks that I had are now locked again.

yep same here: weapons show 0, no names,, rank etc. for teammates when starting a match, some challenge icons are plain text.. thats just what ive noticed so far and can remember. 

Since this new recent patch, two consistent issues that people across chats keep talking about (see above title).

1. Orange Dot for new content or weapon unlocks - broken, can't refresh game to reset. Honestly a stupid feature that can't be skipped wholly and requires manual clicking to remove. Worse is that now the dots are inconsistent and do not refresh.
2. Level Displays Not Showing - have to click into gun to show level. Otherwise, displayed as "0." Very annoying and surprised it has taken this long to patch it. I can't imagine COD has the same issues persist for this long...

Just noticed all my guns are at 0 now, not sure if happened after buying a BF package with new guns inside. I did a reboot, and thought all was fixed for a second, showed XP for guns, but not all guns were there. Few seconds later all guns are there, but every gun is at 0 now. So now it explains why Im getting killed quick at level 111. 

Hopefully someone from EA see this.

I saw this too! i noticed it on all the classes but not in the FAVORITES area. Adding to the FAVORITES will allow you to see the gun level.
