I am currently trying to upload a map to my fileshare but it wont let me, i can upload everything but maps
yeah, I had the same problem last night. It just cleared itself up, just give it a while; max a day or two, and you should be fine. No real problems, just a glitch in the system.
There is a large thread talking about this in the Halo Forge discussion. It explains everything and how it works, next try using the search bar and looking in other possible sections before posting a question thats already been answered. Now, this is caused by bungie removing the halo reach data from the servers, and it basically messed up some code that allowed us to upload or download ANY data within halo 3 or ODST. Just wait for bungie to correct this and everything will be good.
