I don´t recive the b oss coins....
There is a central topic where you can post which achievements you should have gotten.
Here it is: https://forum.onlinesoccermanager.com/topic/9049/achievements-bug
But who can i solve the problem?
Gamebasics are already aware of the problem and are working on fixing it. If you post in that topic which achievement you are missing they can track it once the bug is fixed and give you the Bosscoins that you are missing now.
Unfortunately patience is the key here, because we can't say when it will be fixed.
Only that they will try to do it as soon as possible.
