I’ve recently purchased the digital version of MCC and installed everything – 72.2GB. Then to play halo 3:ODST I had to purchase this add-on on MS Store and download additional 10MB. But when I’m trying to launch ODST campaign I get the message that the content is not installed, even though it’s marked on the installation screen as installed. I’ve already reinstalled hallo 3:ODST campaign and even the whole game but it didn’t help. My MCC version is 1.559.0.0 (updated on 11.10.2018). Please help!
Ok, I’ve found the workaround. When I switched game language to English it has downloaded additional hundreds of MB to halo3: ODST and halo4 campaigns, so now the full installation size is 72.9GB. Since then I can start halo3: ODST campaign – it doesn’t say it’s not installed anymore.
So, it seems to be the bug in Polish version of MCC.
