Advance error with tbamud2020

Weird it didn't happen this time. I don't know what i did but it is letting me now.

The SIGUSR1 is used by the autowiz system; when a character is raised to immortal, the mud calls out to a separate program about updating the list. Then that program calls back to the mud with a SIGUSR1 to trigger the mud reloading the wizlist file.

This isn't code that has changed in a really long time, so it's surprising if that code is problematic. However, the rereading of wizlists involves freeing and reallocating memory, opening, closing and reading a file, updating pointers, etc.
This means there's a lot of changes happening which may fail - perhaps due to other things that have changed over the last ten years. I suggest looking elsewhere in the stack trace to see what is failing. This will make it easier to find out what the problem really is.

...Not the apply one but the one that you enter when changing damage dice...

That one is read directly from the weapon when trying to hit.
