"address" isn't anywhere in that code. Do you have multiple Login() procs?

To help, could you put #define DEBUG in your code so the runtime errors would be more specific?

I can see two things wrong with that (well, one is kinda...)

1) src.mob.client is the samething as src here, as you are saying client.mob.client, which refers back to itself. You could've made it src.Save() and it would work the same.

2) In point#1, delete the whole line (yes, the whole "src.mob.client.Save()" line, or "src.Save()" if yopu wish).

The reason is simple. client/Del() is called when the client already left, so when the savefile tries to be exported, you'll get another 'null.' runtime error, because the client is already gone thus nothing to export to.

3) As Kaiochoa said earlier, put "#define DEBUG" somewhere. What this will do is, when you get a runtime error, it'll give you the file and approximate line the error occured at.

Open Admin.dm and press CTRL G. Type in 5 to go to line 5, and post the procedure that the line 5 is in.

We need to see the whole procedure that line is in so we know what's going on.

The worst thing you could possibly do is delete the line that causes the problem. That would lead to even more problems.

Besides, if you're trying to do a check for the host to get verbs, as of BYOND 4.0, there's a world host variable containing the key of the host.

As quoted in [link], it is always wise to safety check: 
if(!Host && src.client && !src.client.address)
   Host = src.key


It checks first if Host is defined. If it isn't, it'll check if it has a client. If it does, it'll check if the address is null (you should also findtext() for "192.168." or if it == "127.0.0.1" as they are internal IP addresses).

And, if you do have BYOND 4.0, you can do what Kaiochao mentioned in [link] and use the variable "world.host" and scrape the host-setting lines you may already have.
