When are halo 2 co-op crashes going to be fixed?

Seriously 343, it’s been well over half a year now and most levels in halo 2 co-op still crash after trying to load. Makes getting a few of the achievements an unnecessarily long, frustrating process.
Surely you aren’t just focusing all attention on halo 5, that’d be like ignoring one of your children.
If i get a response from a community manager that’d be the best, i am looking forward to halo 5’s story and returning characters

Nrver. 343 doesn’t give -Yoink-!
