One character has reached level 15, but the achievement was not given. Error? How to get this achievement?

I'm sorry, but this looks exactly like Kingdom Rush, just with "modern era" units...errr. Seems pretty lazy to copy the work of another studio if you ask me. What would make this even special?

Level up a hero to level 15 Level up all heroes to level 15 Level up all towers to level 5 Finish the game these achievements don't work for me???? I finished the game with every hero level 15 all towers level 5 (also placed all of them and upgraded them to level 5 in a single battle) all stars at every level and all hard modes I even played all the side missions that keep on going atleast once, Are the achievements going to be fixed or can somone dive into the games codes and find it out??...

Hello, Basically what I want to know is are the dev's attempting to fix the bugs in this or have they moved on leaving it as is? If they're still working on this then great I'm happy to wait and provide bug data when needed but if they are not I think it's a poor show and I intend to include this information in what would of otherwise been a thumbs up review....

we have notice the game does not save
