I had this happen too. I died nearby my trailer in MP, and when I respawned the first time on my body my trailer (which was attached to the car I had) was gone.

I've been having this problem pretty often as well since the new update. You lose sight of the trailer for going a bit too far from it and boom - It completely disappears until you rejoin the server.

The trailer can also re-appear if you die, but it won't be attached to the car anymore, instead, it will teleport back to the place where it originally disappeared (Which can be annoying in case you moved your car ), but it seems like after rejoining it will be once again attached to the car.

This also happens with trailers from other mods, such as the KI5's '92 Humvee, so it might be just a more general multiplayer bug.

happens to our small group too, when somebody doesn't see the trailer we have to reconnect the trailer so everyone can access it again. restarting the server also works to make it reapear

I downloaded other Tsar Automods and it changed every trailer into vans or trucks that you cant drive

Did you find the solution? With some friends we have a server in Nitrado and the same thing happens. Sometimes it teleports after a short time or sometimes it takes a little longer, in some cases we find them out there. Sorry for my English.

I have not found a solution, the only thing that seems to work the best is disconnecting the trailer whenever you leave your vehicle in an area and reconnecting it before leaving.

at first our camper started disappearing and would reappear on relog, after some time it disappeared for both of us while towing..

The same thing happened here, dedicated server with my friends, we lost sight of it and it disappeared with all the loot from the police station q.q, I'm reconnecting to see if it changes

My friends and I were able to make the trailer reappear by having someone else (other than the last person to do so) drive the car. Once they move the car, the trailer reappears.

This is the vanilla bug (i.e. desync issue).
Someone, who still sees the trailer, should connect or disconnect it.
