When a critical error occurs in the game, a text file is generated with information about the error and the information needed for debugging. If you are unlucky enough to encounter a critical error, please send the HD_CRASH_LOG.TXT file (located in the game folder) to the email address: baratorch@yandex.ru, or post it here on the website. This will greatly help in fixing the error in future releases of HoMM3 HD.
If you are interested in fixing bugs, please provide detailed instructions (a sequence of actions) so that I can reproduce the bug. General statements, such as "there is a very bad bug," are of no use. If the bug cannot be consistently reproduced with the same sequence of actions, it is extremely difficult to fix; however, the more detailed the description of the situation in which it occurs, and the more information about what preceded it, the better.
Also, to fix the error more effectively, a save file may be needed, which you can attach to your message as a zip file.
