Some of you have probably experienced issues with multiplayer after the latest update. We are aware of them and we devoted our time towards solving some of the most common ones.
Vehicles through server
In the past every time a vehicle was spawned, data had to be sent directly to the other players. This data transfer didn't always go as planned and in some cases people couldn't get in their vehicles, the server had to be re-hosted and so on.
Recently we decided to make additional changes and send the vehicles through our server first. Instead of direct data transfers between players, the vehicles are uploaded to our servers and then passed on.
This approach is more reliable than direct transfer because it'll fix some of the most common issues. On the other hand once a vehicle has been spawned re-uploading it won't be necessary and therefore less data has to be sent.
Connecting
The update won't change anything about the way that you have to connect. Hosting a server still will require port forwarding in some cases whilst joining one won't.
Additional multiplayer update next week
One of the things you'll notice is the fact that your vehicles will disappear every time someone joins a server meaning that you'll have to respawn. We made it this way for now to ensure that nobody receives outdated data and it's something that we hope to eliminate in the next couple of days so that an additional update can be released somewhere next week.
