Piglins are not always attracted to gold ingots/gold items

they made it so if you left click on them while holding the golden nugget they trade with you

No, that's not true

 Piglin's are only attracted to the gold ingot if it's in the piglin's line of sight. What you did was, you put the gold ingot one block below, and the Piglin couldn't see it.

Even then he's not always attracted. That's the bug here.

in fact piglins don't trade whit anything item of gold regardless of whether the gold item was dropped or right-clicked, even with gold nuggets they just shake their heads down but don't pick them up, plus they disappear without the piglins exchanging anything

Still in the latest version
Expected Results: they should be attracting the golds
Observed Results: They ignore golds that are dropped

ye it happened to me too

Affects 1.17.34

Affects Bedrock 1.17.40, playing on Windows 10, realms or locally. 

Some additional info from my testing:

Piglins will trade if right clicked with gold in any circumstance (that I've tested), however when restricted in some way (that appears to be a bit inconsistent) they won't pick up dropped or dispensed gold. The most robust way seems to be a 1x1 hole at feet level (though lower half slabs don't necessarily have the same effect). That seems to be usually true whether its a 2 deep hole or with a block above their head to prevent them jumping out, with gold dropped from above or landing next to them 1 block above their feet. When blocked at head level they still appear to behave as expected. There seems to have been a change at some point, maybe around 17.3x, as an auto piglin barter (in a 1x1x3 hole, stood on carpet on a hopper with dispenser directly above) that was working has stopped completely (in survival or creative). If I see any other patterns I'll add more details...

Thanks,
