Pump Shotgun ammo switching crash

Platform: PC

Description: Switching ammo twice in a row with the Pump Shotgun crashes the game. Though the issue does not persist with other weapons including the Granatgevar or the Sjogvist Semi-Auto and location is irrelevant. This crash is overall pretty persistent however the ammo type that you switch to specifically is also irrelevant.

Steps To Reproduce: Switch ammo twice in a row with the Pump Shotgun. I believe you need at least 3 ammo types available for the game to crash.

Didn’t do that for years.
Mostly had 2 types of ammo in m inventory.
Birdshot and exp. healing ammo.
Which class of the 12G did you use? 1c to 5c or the 6c?

I’ve had the same issue with the S- 21 firing Shock, when alternating between FMJ, AP, and Shock.

At least with my 6c AG4, 6c Kvm59, 5c AI76 and 5c PM71 (my prefered 7.62 guns) I never had this issue.
I always pick up anything I get of 7.62 and carry some shock ammo, and often switch the ammo.

Maybe not often enough… At least I never had a crash by switching ammo.

Oh, the same with my 6c klauke and 5c N9 an 9mm handgun ammo.

I’ve discovered the crash with a 4C. Upon seeing this I’ve also tried replicating the crash with a 2C Pump and a 4C Semi-Auto. The game didn’t crash. I’ve also done more testing and the slot the weapon is in is also irrelevant for the crash. Attachments are also irrelevant.
