Bug reports.

Sometimes, when creating a game in Heroes of Might and Magic Online, the initialization process glitches, and players partially see each other and partially control each other's actions (I've seen this a couple of times on streams). The cause is not yet clear. At the very least, it's definitely not recommended to connect to someone who created a "new game" through "load game," and vice versa. If there are any strange occurrences in the game, such as something switching on its own, the screen flickering, etc., it's best to recreate the game immediately.

Not everyone knows yet that there are no autosaves in Heroes of Might and Magic Online! There are only saves at the beginning of the turn.

Autosaves should be normal. Perhaps the checkbox for saves in the HD launcher is disabled, or it's another bug.
