Well that’s not true. It’s just a real bitch. As a welder, helium leak check is about the toughest damn QC to pass. Most welding QC has some reasonable margin for error during inspection, but the damn helium doesn’t care. You can have a beautiful weld with a tiny imperfection at the start or end and it’ll piss helium just as badly as an entirely scuffed bead.
Skyrim did it first with dragons. Honestly I bought palworld specifically to spite shitendo and ended up pleasantly surprised by a very playable game. Shitendo is just mad that someone else did it better on a shoestring budget
