I just started TR4 last night so I'm not very far in yet - current on Temple of Karnak - and I just picked up the shotgun...for the FOURTH TIME.

Does Lara keep losing her weapons or is this a glitch or something? I've only used Laras dual pistols so far so I haven't ever USED the shotgun so no idea if it's dissappearing from my inventory.

But, yeah, this is the FOURTH time (usually upon discovering a secret) that I have picked up a "New" gun only to discover it is yet again the shotgun.

Absolutely nothing works? I've looked it up and it says to hold the dash button and that doesn't work. However, it ALSO doesn't work when I'm trying to sprint (ditto for Chronicles).
Lara WILL NOT sprint or rope swing?
