Random Props Disappearing in Specific MLOs - Intermittent Issue with Encrypted and Open Source Mappings

Hello
I have a problem with some objects (props) in three different MLOs, including two paid and encrypted, and one free open source. Randomly, some props disappear for players, and reappear after a reconnection. The problem is random: sometimes a player sees the prop (such as a desk or a closet) while another player does not see it. This phenomenon occurs in the three MLOs, but the props affected are not the same from one MLO to another.

To reproduce the problem, simply go through the map in noclip or move from one point to another. Sometimes, when arriving in one of the MLOs, all the props are visible except one which is always missing under certain conditions.

What I tried:

• Launch an empty server with only mappings.

• Test an empty server with only the mapping where a prop disappears.

• Try all available game versions with an empty server.

My game version is 3258, and my server version is 7290.

Dont no clip into any mlos, game doesnt like it

Potential causes

  1. There are props not assigned to the correct room in the ytyp or placed in a ymap and not the ytyp.

  2. Conflicting maps

The only way to test this is to have vanilla server and only one of the problem maps ensure/start in server.cfg

Test each one individually to see if it is working correctly.

Then add two and test etc

If the mlo is not working correctly as the only mlo loaded, you need to go back to the seller

Thank you for your suggestions.

I have already launched a vanilla server with only the problematic MLO started via start in the server.cfg. Unfortunately, after several turns of the map, the problem returns: some props end up disappearing randomly.

I also contacted the sellers of these MLOs (I prefer not to mention names, because I do not seek to damage their reputation), but despite their notoriety as a studio, I did not receive any support from them. The problem also occurs in a free MLO, and I verified that all the props are well placed in a ytyp file.

I still don’t understand why this is happening and I would like to know if other people encounter this kind of concern.

To clarify, I use the noclip as a debugging method to reproduce the problem more quickly. When browsing the map in noclip, the props often end up disappearing, which allows me to see the bug without waiting for it to manifest itself randomly. However, the problem is not related to the use of noclip: players on my server also encounter these disappearances of objects while they play normally, without any use of noclip.

A common issue, even for the more popular and seasoned MLO creators, is that props, usually base game props, will be called in multiple ytyp files, and props only need to be called once by a singular ytyp. Usually, if the prop is a base game prop, is doesn’t need to be called as an archetype in a custom ytyp. This will lead to those props disappearing from other MLOs that happen to use that prop.

Thank you very much for this explanation, it could indeed be the cause of my problem. If I understand correctly, the same basic prop should not be referenced in several ytyp files, and ideally, it does not need to be defined as an archetype in a custom ytyp. This could explain the random disappearances of the props in the different MLOs of my server.

Do you have a clear idea of how I could verify this effectively? For example, is there a way to spot conflicting ytyps or a method to test which props should be excluded from custom files? Any help or recommendation would be welcome!

Use the program Codewalker to edit ytyps and view their contents.

So I have to remove the props from the ytyp

never had that problem ever

Yes, if it exists as an archetype. Look for tutorials on how to create and edit ytyps.

It happens pretty frequently, but not all the time, when base game props are used as archetypes in custom ytyps. I have seen Michael’s house stripped barren due to this. I have also seen creators call the same custom prop in multiple custom ytyps used for different MLOs. This led to the custom prop appearing only for one map. Sometimes the props used in the instances described above will be located where they are supposed to be, sometimes not. Sometimes they disappear over time.

Hi, when you say “if it exists as an archetype it must be deleted” would you have an example please in order to understand? Thanks
