Having the same issues - massive lag and animation freezing during both the buy and combat phases. The problem is getting worse with every new patch, and is resulting in the game freezing up for 30+ seconds every turn, combat taking twice as long as it should, buy animations stuttering and misplaying, seconds disappearing suddenly when there’s 5-10 seconds supposedly left on the timer…
Its really frustrating, to say the least. It is not my PC, its not my internet connection, its not ‘needing to update Battlenet’ - its clearly issues on Blizzard’s server end. Makes the game basically unplayable beyond turn 8 or 9.
