##### **Greetings, heroes!**

In this update, we’ve focused on bug fixes, improving network stability, and balance adjustments.

Critical bugs affecting campaign progression and AI-player behaviour have been fixed, and errors in creature and object stats have been corrected.

The network is now more stable — we’ve improved lobby entry, the reconnection process, and client synchronisation. In multiplayer, we’ve adjusted timers, the “Diplomacy” skill parameters, and the cost of several Hive faction buildings. We’ve also made adjustments to hero skills and fixed localisation mistakes in several languages.

We keep actively working on network stability and balance — there are many more improvements to come. Thank you for your feedback and bug reports: it is thanks to you that we can make the game better with every update.
