We have deployed a fourth hotfix in response to the latest feedback.
Please ensure the version shown on your main menu is "4.64" before giving this a try.
This hotfix is built on top of 4.6 and the earlier 4.61, 4.62 and 4.63 changes.
Thank you for trying the new multiplayer systems and for your feedback. Our new Steam Multiplayer systems should look more robust now.
We have performed even more tests along with the community. The following more intensive tests on vanilla were performed and never resulted in any apparent game-breaking or loss of synchronisation issues:
Playing with speed set to maximum
Playing through Council and Trial cutscenes
Performing various actions and actively playing rounds
Starting new fresh games
Loading 4.64 save games
Triggering a Resync request and successfully recuperating synchronisation
Using the in-game chat system
Playing with more than only 2 clients running
Using different languages accross clients
Previous save files should be compatible, however please make sure to select the right colour for your dynasty selection. Using AI colours may trigger a Resync.
4.64 introduces a new way to "Share Saves" via the Steam Lobby Rooms directly. Hosts may now ask users for permission to send them the selected save files before even loading into the game. Once all users obtain the save file, the entry into the game should be stable and functional and should not trigger any game-breaking issue.
If any of the clients do not have the save file, the system will fallback to the Resync method when starting the game. The Resync method is what is used in most regular scenarios, where something could go out of synchronisation during a live game.
We have temporarily disabled "Mid Game joins" as this new system requires further fine-tuning.
Improved on the Steam Multiplayer systems for better stability & bug fixes.
Fixed an issue whereas the game would infinitely loop the saving process of save files if the user pressed the "ENTER" key on the keyboard while the Text Box used to type the name of the save file was focused.
Fixed an issue whereas players could assign EXP and Skills to non-family NPCs they have control over.
Save files can now be deleted again.
Probable fix to new buildings sometimes not being assigned to your characters.
Fixed some maps previews in the Steam Lobby Room not showing properly.
Added "Share Save" feature in Steam Lobby Rooms.
GiTSE / DBTEditor instability.
GUI elements flickering or acting strange when returning to the main menu (old issue).
Occasional black screen when returning to game after alt-tabbing.
In the building statistics UI, sometimes the amount of an item sold is incorrect.
Short game freeze when opening the "All" categories of the new City Needs UI.
Sometimes, the following happens: "Waiting for players" pop-up hiding behind the main menu when returning to the main menu after leaving a Steam MP game.
Sometimes, if the host disconnects from the ongoing Steam Multiplayer game, the clients might crash.
We would like to thank you for giving this beta patch a chance.
Please let us know if there are any issues that were not yet resolved, and please also let us know if this fixed some of the issues you were having properly.
Thank you for your patience!
