That is because the kernel table for that game is not complete. There
are two solutions to this problem:

1. Use a special patch file for VOCAB.999
2. Edit the fallback table in src/scicore/vocab_debug.c

For #1, you can extract the one from QfG2 (for instance) and place it
in the Jones directory.

#2 is the right long-term solution. I'll look at it tonight.
