Cars Despawning/Wall Despawning

Try using the value 3888000 for lifetime, this is 45 days.

This is the default max value Bohemia suggests.

Sorry, can’t edit former post!

Correction of limit mentioned above :

9999999. (7 digits)

Assuming that you had this issue prior to changing lifetimes to an ignored value. My experience with this leads me to think it is simply the core file with a persistence rule corrupted. I have had several members of discord run into this. The going solution has been..... wait for it.... a re installation. I know, it is every ones solution at times. But, I know it to have solved the issue. Save you XMLs that you have access to, and then reinstall. Save them to a PC first, as we know there to be a bump in the process that sometimes overwrites your XMLs without having selected the option.
