New here? I'm Roha — want a quick tour?
We played with Izgoy h3dm1 using simultaneous turns up to turn 117. On turn 121, the system indicated that simultaneous turns were ending, but for me (blue), all heroes were still active and could take turn 121 without waiting for the red player to finish their turn. After completing the turn, there were very brief, almost instantaneous, glitches with the display of the opponent's hero. I had to reload the game and continue from the blue save at turn 117, after first unchecking the simultaneous turns option. And yes: the system automatically sets the end time for simultaneous turns to 120 after the start, if this information is important. We were playing on the latest HD mod 4.100 RC4. Unfortunately, I don't have the saves anymore, as the checkbox was reset after the update.
HoMM3 HD 4.100 RC4
+ Now, after installing the full version (4.100 RC4 and higher) on top of the old one, it is possible to revert.

Hed-kun, what is this ERA 1.19 you're talking about? It seems like the problem lies within it.
