Okay, i was playing earlier today and i encountered a bug, very big one in my opinion.
I pre-ordered the game, and got the weathered pistol, then i modified a laser sight to it and this is what happened...

This, is very annoying....

Whoa...just a big exclamation mark smack dab in the middle of your screen? These bugs are ludicrous.

Looks like the mesh for Modified 10MMs have been lost along the course of development. I believe this is the gun from the Classic Pack? Has anyone tried modifying a Sturdy Shotgun to see what happens? This could be linked to DLC or it could simply be a lost mesh for this lone weapon.

This classic pack seems like it's just a big mess of problems. I'm wondering if it has anything to do with the save game ending bug.

May I ask, what other problems have been encountered with the Classic Pack? I'll be getting it as my pre-order bonus from GAME on Friday.

I can't help but laugh a little bit. I mean really. WTF is THAT!?

For now, I'd suggest rolling back to a save before the weapon was modded. I've passed this along to our team so they're aware of the issue.

Yeah, I was just about to post a topic about this until I found yours.

I'm playing on the 360 and my game did this when I attached the extended mags mod to my weathered 10mm pistol form the Classic Pack.

Yea, i think it's just with the Classic Pack DLC, other than that the only problems I've had were lag, and characters/creatures going through the ground.
