The xbox achiements Castle Crasher (complete 5 matchmade games of strongholds) and Flag Monger (complete 5 matchmade games of ctf) are no longer unlock-able. i have played several games of each and no credit has been made towards the achievement In short I presume its because those modes have been lumped in btb, which has crippled the functionality of related achievements.
Same issue here
Have you tried playing CTF and Strongholds in Team Arena?
They aren’t only in btb. Try team arena
