Whenever I subscribe to a mod of considerable size, such as a campaign map, the addon always has the same problem when installing. It will install for a while, before all addons stop installing completely. The only way to get it to resume installation is to close the game and start it up agan, at which point the process repeats. Does anyone know why this happens? Incidentally, I'm aware of and use L4Dmaps, but not everything that's on the workshop is on there I find.
