Sometimes things disappearSolved

I have players here and there report things missing from their backpacks. doesnt happen that often but it happens. any help would be appreciated :)

Are the users reporting that specific items are missing, or that all the contents of the backpack are going missing?

I'm not aware of any issues that could cause item loss with Backpacks. Some time back, there was an issue where all the items in the backpack could be lost in some rare circumstances, but that was fixed.

As for what could theoretically cause it, I would have to ask if it's specific sections of the backpack, like specific pages, specific rows, specific item types. Any and all information relating to the item loss is helpful, including when it happened, what the user did before it happened, etc. Given a significant amount of such information, we can look for patterns and I can generate theories as to what the issue might be. If I can't reproduce the issue, then I would have to resort to making experimental changes to the plugin to help narrow down the issue, as I did with the previous item loss issue (which took months to resolve).

its only specific items, mainly guns like m2's etc. it can be random slots in backpacks as well. doesnt seem page specific, but usually just the first page. 

It's happening again this wipe to more ppl, they will log off then log back in to half their guns gone, mainly m249's and l96's that are mainly noticed but happens to other guns as well. It's happened to at least 5 ppl so far and I get heat for it. lol

Hasn't even happened to us in 2 years. There are players who take advantage of that and just say it's gone to get stuff. Are you sure that's not the case?

It has never happened on my server since this plugin first came out , no complaints ever

If you are referring to https://umod.org/community/backpacks/48711-users-reporting-backpack-items-disappearing, that issue caused the entire contents of the backpack to go missing, not select items. It only happened in extreme edge cases which I could never reproduce. It was also fixed.

No matter how implausible or suspicious the user's claims may be about the items going missing, I will do my best to offer advice on resolution. First, we should document the circumstances around the reported item loss. Absent very verbose logging which could significantly affect server performance, we can start by using an informed understanding of how the plugin works, combined with detailed accounts from players, to see if the ways that items could technically/theoretically go missing are matching the reported anecdotes.

While a player's backpack is loaded in memory, the items are stored in an actual storage container, basically the same as a player might place in their base. Items don't go suddenly missing from storage containers unless players take them or if a plugin somehow interferes (prevents the item from going in, or takes it out). When the server saves, the items are serialized to JSON and saved to a data file. If the player is not connected at that time, the storage container is deleted to save on memory and entities. When the player opens their backpack after the storage container has been deleted, the storage container is recreated from the data file.

In theory, something could go wrong with the saving or loading process. If that happened, you would see errors in the logs. In the case of failed saving, the player's backpack would remain as it was saved in a prior iteration, meaning recent changes to the backpack contents would be reverted, such as items that were recently removed still being present, or items that were recently added being missing.

If the affected players can provide more detail about what they saw before and after the perceived issue, as well as the timing of opening, disconnecting, and opening again, that will help move the investigation forward. The more detailed and precise the data, the more helpful it will be in pointing to or ruling out potential root causes. Additionally, if you haven't already reviewed your server logs for errors, please do so now.

Ok, your missing the point that it happens to players on my server. Your experiences don't matter. Neither does your opinions, this is a ticket with white thunder, not nosey know it alls that need to add their 2 cents.

I'll make a ticket in umod discord. It's rather annoying having other users feel the need to talk down to others or add their 2 cents where it's not needed

It's all good tho. I'll just start telling players with missing stuff that they just lying according to umod. 🤣

It is a fact that such a thing happens. And when players get away with it, word gets around. It was just a well-intentioned piece of advice to keep this in mind. But if you think it's not like that, then fine. Good luck with your troubleshooting!

uMod Discord doesn't have a ticket system. You could DM me on this site, but I strongly suggest using the forums (this thread) as that allows others to contribute to and/or learn from the discussion.
