If you use the auto-fire mechanism with Trigger Happy, you’ll get up to 3 shots when it goes off. Still can’t switch to burst though.
As for the gas, I remember reading that filling a container has a 1 in 50 chance of breaking the pump. Filling a vehicle also has a chance of breaking the pump, but the chance is checked more often, meaning you can get 40,000 units in a steel jerrycan without breakage but only 2,000 by directly filling a vehicle.
I’m also having trouble saving artifacts, whether they’re on the ground or my person. They show up as ‘none’ every time.
I think bladed weapons getting stuck is broken as well. When a weapon gets stuck, you lose 3 turns. My katana gets stuck EVERY swing, at 13 str and 6 cutting skill. Katanas shouldn’t get stuck. A broadsword, wood axe, or cleaver, maybe. Anyway, cutting weapons get stuck so often that there’s no point using them. A baseball bat will outdamage a katana every time.
