Ok I bought GMOD within the last week, and then a friend bought it as well. We both installed a bunch of the same addons (various maps, vehicles, NPCs, entities, etc). When either of us creates a multiplayer game, with the only option changed from default being the “local network game” since we are in the same room/network, the addons we chose are not available…well most of them. Like the entities addons are there, but the vehicles and NPCs tabs only has the ones that came with GMOD. We tried it without the “local network game” option checked, but it still is limited in addons available for use.
Also the game shows up as [L]Sandbox in the multiplayer list, although I found that means its a listen server rather than dedicated server.
Any ideas why it does this and/or how to fix it?
