I had a lvl 30 character that I deleted to re-use the slot. The new character in the re-used slot seems to have been given credit for all the weapons and intel collected by the original character in that slot, while not actually having the items available. I use intel and do not get the option to see weapons (if the old character had collected all weapons in that zone) or a limited range of weapons (those which were not collected by the old character). If I just go the location for the weapons I cannot get the intel for, I see the weapons box but cannot interact with it. The only work around for this I have found is to delete the saved game folder and flat out restart. This seems like a bug to me.
