2 Survival Bugs

Just a reminder of these two bugs In survival:
1. Upgrading the Panzerfaust a 3rd time (to 3/30) works for 1 shot, then stops working completely via won't reload.
2. Ressurection (regular & pro) doesn't always work - i,e, I have regular and/or pro version for the perk, get killed, and turn "invisible" yet I still get shot at... the only infrequency is the amount of enemies shooting at me while I'm apparantly invisibile - sometimes it's only a few, sometimes its all them... which a lot of the time deems the perk useless, as I'm trapped behind a lot of soldiers and die.
Thank you!
