Buying from the tader with a (nearly) full inventory...

[Broccoli Clock]

Had a quick look at the bug tracker, thought I'd start this thread to double check if what I experienced is what others do. If so, I'll start a new bug report.

In short, if you buy from the trader and don't have the inventory space the items you bought "disappear".

I bought, 144 potash (2x64, 1x16) using up all my gears. I didn't realise this but I only had one space free in my inventory. The trader took all my gears, but I only have 1x64 stack of potash and the remaining 80 vanished into the ether. It's not on the ground, and the traders has cancelled out the potash because they'd sold me all they had.

* sad trombone *

Is this recoverable? Have I lost both gears and the majority of the potash?

You sure the trader sells that much potash at once?

[Broccoli Clock]

It showed up in the trade bar at the bottom, when I clicked sale all the gears were gone and I had the exact number of gears for the amount of potash they had a supply off, with the red cross appearing immediately after buying it.

If I had to guess, and it is just a guess, the items were bought then "lost" because whatever code handles the transaction doesn't check if you have inventory space. That's no shade being thrown, I'm a coder myself and this sort of stuff is all too easy to overlook.

Hence the thread, see if others have experienced similar, if so I'll try to replicate it and create a new bug report.

Are you using a trader mod? That's triple the amount I've ever seen. Not that it changes the possibility of losing stuff, but I don't know I've ever seen one full stack available. And, of course, I always check the commodity trader early and often because, hey, potash.

Nope, vanilla.

It may be the way I bought it, I dragged the potash to the buy slots, but was also right clicking it to increase to the amount I want. The gears were in my inventory, when I pressed sell all the gears were gone and the slot it opened up had a stack of potash.

Perhaps it's the odd combination of drag and right click to drop the items into the sell bar affected the amount it sold, or perhaps the amount it sold it for. If I am in the position of having some gears (heh, I just spent all of mine on potash!) I'll try and recreate and replicate/record it.

I'll be honest, as the trader had taken the gears (I think it was 28) and I ended up without the potash I just went into creative to give it back to me. I really don't like doing that, but I felt it was fair considering the gears were taken.

Oh, I didn't know you could do that. Never tried, I guess.

Definitely a bug, There's little point in having them in lots if you don't have to stick to the lot size. Does it work for selling, too? That could be a serious exploit. Potentially hundreds of rusty gears profit per trade if you can buy and sell multiple wolf pups, for example.

Got to admit I have no idea, I don't use the traders all that much, and I wasn't really paying attention to this one. I wish I did, but how I've described the interaction is about right.

As you say, likely a bug, possibly related to how I used the UI. Thanks for the feedback.

If you don't Travel too far they will set on the traders floor for as long as your settings for dropped inventory items before disappearing.

I've not realized in time and ran back and they were gone.

If you have longer settings for dropped items and they were gone instantly then it was a bug or a mod.

If they had fallen on the floor, could the pre-1.20.5 version bug of items sinking into the ground have made it seem like they weren't there? (I didn't see mention on whether you'd updated to the latest version which fixed that bug)

Yeah, it's the first thing I thought of. I was inside the trader caravan when I made the trade. I looked on the floor, looked under the caravan but obvs I can't dig under there. It was afternoon, so the light was decent, but there is the possibility that it "blended into something". I did the classic 'pacman style' searching, hoping to hear the pickup sound even if I couldn't see what I was picking up.

My timer for things remaining after death is 30 mins, I think that's default, and I presume that's the same time for dropped gear in general? Perhaps a modifier based on if you are in the same 'chunk' or travel away.

It could totally have been dropped, I certainly wouldn't rule it out. As I say, if I can try and replicate it I will and I'll throw up a bug report.

Had you already updated to 1.20.5?

It does sound like your pacman-style searching would have found them though. My thought [eta: assuming you're on 1.20.4] is that the floor of the trader caravan may function differently than other surfaces we're used to, and 'maybe' the items could have settled on the ground below the trader or even within the ground below the trader (due to the settling-into-the-ground bug). If that is the case, it would take being in no-clip fly mode to find them.
