On a second note there's something else I noticed with respect to this. Some container kept their contents while others lost theirs. In hindsight it might be the items that I placed into the container while holding the container itsself in my inventory. It might be that the ones that were placed into the container after that had been placed onto the map, that dissolved. That would also suit the "You should not leave something here" messages that kept popping up.

I have tried it again and can confirm, my last suspicion. Placing items inside containers, which have already been placed into the world, lets the items disappear after a while.

Placing them there, while the container is still in your inventory, lets the items stay in the container, also when placed in the world afterwards.

I cannot reproduce this bug. What container are you using? The only containers that may delete/destroy items, are the ones like a furnace or forge, surely not a closet.

These were two door closets and they are placed in the GH3 map/instance (guildlaw/15263749; on the far right mezzanine when coming in).

I investigated more on this problem. Whenever a container is on the ground, and player adds an item to it, the item will become guarded by him, so none else can touch it. But (mainly for guildhouses) we decided the item cannot be own for ever, so there is timer of 10 minutes that starts when you put the item in the container. After this timer expires the player gets the message: "You probably should not leave xxx here" and this also makes the item pickupable by other players. Items are never destroyed or deleted through this process. So if you lost items, must have been something else.

The fact that the message about unguarding occurs may be entirely unrelated. Assuming otherwise – stating that since unguarding happens and unguarding can't delete items – the problem doesn't exist is a logical fallacy.

Fact is, that I did lose items this way (this way being putting them in a container previously set up inside a guildhouse) and I did loose all of them – a large amount of at least two dozen items or stacks of items. when I put them there after the container had been dropped.

One circumstance that wasn't tested as far as I am aware: The problem might be related to unguarding with respect to the fact that the container itself is unguarded after a while and is unguarded before the items inside get unguarded, because they were put in after the container was dropped.

But again, the bug making things disappear might not have to do with unguarding at all!

I've managed to figure out how to replicate this particular bug, and it still occurs in the latest version (0.7.44).

To recreate, you simply have to do the following:
1) Place a container down
2) Put an item into the container (the item must be put into a slot in the container after the container has been placed down or the item won't disappear)
3) Wait for (or cause) the server to crash (the server itself must go down - simply logging out and back in again will not cause the item to disappear)
4) Rejoin once the server is back up: the item will be gone from the container, and will not have reappeared in your inventory (it is now gone forever)

My guess is that this happens because a container only correctly "remembers" items put into it before it's placed down. Items put into the container after it's placed are "forgotten" by it upon a server crash, resulting in those items disappearing (any items that were already in the container when it was placed down will, however, be safe.)

I'm hoping this helps with tracking down & solving this issue.

I released a fix tonight on containers which I think will also fix this one, can you please test this again.

Currently testing the fix with Mohonin, please do not close yet.
