Idk if this is necessarily a bug, but I'll post it anyway.
It turns out that stake rules are determined when the run starts. If you start a gold run in experimental and then switch to the live version and continue the run, it's basically purple stake difficulty. The -1 hand size and expensive packs don't apply, and the perishing and renting doesn't exist.
Use it if you're desperate? You're really just cheating against yourself 😛
