Was playing Banjo-Kazooie: Nuts & Bolts, and anyone who've played the game know how freaking painful it is to get the Jiggillionaire! achievement (collecting all 131 jiggies). So I spent my entire free day today to mop up all the stuff I was missing, specificly T.T. Trophies in various challenges. Looking at replays, downloading some new blueprints, and so on. I just completed the final trophy, and my heart was pounding. I loaded up the final jiggie in the trolly, went to the bank, and the TV-Guy gave his speach.
 
Then nothing. No achievement unlocked. No anything. Oh, and the game saved (and in case you didn't know, the game just has an autosave, so no savespots per say). My heart just stopped. I loaded up google and started typing in various searchwords. No reports on anyone having any similar issue. At this point I just thought "alright, so I have to delete my savegame and start over?!". In a last desperate attempt I went back to the Xbox Dashboard, and restarted the game...holding my breath...
 
And yay! As soon as I loaded my save the achievement (and my fancy new Gamer Picture) unlocked! Oh boy was I thrilled, and there's no way in hell I ever change my Gamer Picture now.
