After deleting a room the room the user was in at the time is now giving the below error.

%% Sorry! The code lost its mind while executing a command. Not your fault.
Please send this error information to the admins and tell them what you were doing at the time:
Description: “look”
Error: “undefined method `characters’ for nil:NilClass”

Help!

Oops, it should have moved you before it actually deleted the room. I’ll add that to the bug list.

Going offstage should get you out of the broken room. Then do onstage/reset to reset your last IC position so you don’t get re-broken when you go back IC.

Let me know if that doesn’t fix things for you.

The room with the error isn’t the one that was deleted.

R-128 was deleted, the user was in R-5 and R-5 is showing the error on every command initiated while in that room. (ex: tel, look)

Wait, now I’m confused. I don’t know why deleting one room would cause an error in a completely different room.

Can you please provide the detailed error from the debug log?

I’m not 100% sure the error is related to the room being deleted. But that’s the last thing the user did before the error occurred. Here’s the first error from the log:

Ah okay - that room is set to be a foyer and it’s a bug in the foyer code. I’ll fix that.

To help you immediately, you need to remove the exit that’s leading to nowhere.

I think this will do it:

  • Set the room to NOT be a foyer (teleport to the broken room with a builder/coder char and use foyer off)
  • Find the exit that has a numbered name but leads nowhere - that’s the broken exit.
  • Delete that exit (using destroy <exit name>)

Thanks! foyer off fixed it.
