Nothing else in this thread, just bug reports (to make it easy for the devs to read).

At the bottom of your bug report, you can report your computer specs: CPU, OS, RAM, graphics hardware and software.
Even when I set the game to use my laptop graphics card in the NVIDIA control panel, when I actually enter the game, the "Graphics Card" option in the game menu still shows my Intel onboard chip, without other choices.
Apparently this issue has existed since the beta test. When people turn off the onboard chip, the game would simply fail to launch.
Some report posts I saw:
Old bugs:
- When a dead unit is revived by Regeneration, it immedieately gets full health when it shouldn't;
- The actual damage of Tsunami does not benefit from Master of Magic;
- Stone Spikes deals double damage at the margins rather than the center as the description says;
- Bursting Rage and Fiery Rage issues;
- Dungeon's retaliation issues.
Issues that should be fixed but may be still present:
- Artifacts warping into a different artifact;
- Life Drain does not take effect when destroying an entire enemy stack, and only revives a dead unit when the drained HP can revive it to full health.
New bugs:
- Artifacts bought in shops on the map do not take effect until the player saved and reloaded the game;
- During combat, when a new turn begins, a hero's mana display may erroneously show a larger number than the hero actually has;
- Restarting duels removes the effect of Gathering Storm.
EDIT:
The "issues that may be still present" are probably caused by using old save files. In that case, they have indeed been fixed.
