I played up to level 19 by now. I played level 16 more than 10 times. Still the achievement is not unlocking. What is wrong?

Hello. I bought the whole game incl. 2 dlcs. I had already problems playing the maps of dlc 1. I had many crashes. I noticed that i can manage to play the maps if i only click in the crash levels between the attacking rushes. But when i start dlc 2 the game crashes instantly. I tried to start in easy mode and normal mode. Always crashes in a second. 10 times in a row and rebooting windows 10 x64. Have a AMD 290 with latest drivers....

So, I am having some difficulty completing the game. The Armorer Achievement seems to be just out of reach. Anyone who completed this, it would be greatly appreciated if you let me know how and where to complete this Achievement, Thanks.

plz help

I played like 5 levels into the game and there are some achievements that can be done during the tutorial - Worth it - Unlocked a tile for anchors on any level, but i got no achievement....
