Achievement issue

So, I have the achievement regarding the second audiolog in Halo 3 ODST blocked back from May…it’s been almost 5 MONTHS! And now the achievements regarding the Legendary medals and killjoy medals in matchmaking have been reset! How is this possible?? I was at 225/250 medals for the killjoy and 98/100 for the legendaries…for not talking about the fact that I have already 284 kiljoy medals and 130 legendaries medals, but for some reason the progress of the achievement were showing 98/100 and 225/250! I’m pretty sick about this situation about the achievement, I had problem with them since day one, like the majority of players I think! This game is out from almost one year, when do you want to fix it?? Oh, and I also have a problem with the one regarding not using any veichle in the Halo 3 mission The Ark in legendary,I have done it something like 4 times and never succed to unlock it… I’ll wait for some support!

yea my grenade medals got reset from 92% to 27% luckily though i got my domination ach 2 days ago but i would of been super pissed if that had gotten knocked back.

the ark legendary i have done it and it didn’t give the achievement but apparently picking up or getting on a turret will void the achievement (which i did in my run)

I really want to give up on these achievements. I don’t think battling the reset is worth it anymore.

“Who needs them?”, the achievement for completing the Ark on Legendary without getting in a vehicle is currently glitched and unobtainable.

And yeah, a lot of people (myself included) have lost progress on several matchmaking achievements today. Seems to be a wave of it going around.

I feel your pain my party pooper/ killjoy medals was 187 out 250 yesterday and by the end of the night i have just 5 out of out 250. I went to the medal list for matchmaking i have 405 so mine must have reset twice, the first time i didn’t know about it and recently yesterday. i’ve more than earned that achievement, but i don’t know what to do, can someone at 343 fix it or do i have to win all those medals and matches again ? I’ve taken pictures of the legendary medals for matchmaking as well because i hear by googling they’re known to reset as well and if that happens to me i’m not playing halo mcc and cancel my order for halo 5 cos I’m not play my -Yoink- off on these games just to get reset and have to do it again, just no ! i have picture proof and tweeted members of 343 on twitter about it, other than that i don’t know what to do. If anyone knows please let me everyone else know who i can contact to help me with this.
