Why did you delete all of the already obtained achievements?

This will cause some real anger

Greetings! We will soon release an update and it was necessary to remove the old achivements.
We appologize for the inconvenience.
New achivements that we're planning to introduce will be a bit more challenging and won't have issues. Thank you for your time.

Were there no other ways to frustrate all the achievement hunters e.g. ? Maybe release a V2 of the game or a separely DLC ? If devs decide to change the entire reward system it's a bad move firstly to wipe all scores of the customerbase. I don't see any other changes yet.
