Such issues with games can be caused by problems on the side of the game producer or on the side of the game provider service.
Here's what you need to do:
Enter the game with the currency pair that you selected last time. For example, if your active wallet’s currency was USDT, but the in-game currency was displayed in USD, then you have to go in with this pair.
After entering with the same currency pair, you will pick up where you left off — even if you purchased or won an in-game bonus.
If the problem persists, please contact support team at [email protected] or via the live chat widget on the site — they will help you with this problem, or assign a task to the technical team.
