Bug#877328: mod-animals: crash game in animal_dm/vault.lua:518: attempt to compare nil with number

[Paul Wise]

Package: minetest-mod-animals
Version: 2.5.0-2
Severity: important
File: /usr/share/games/minetest/mods/animals/animal_dm/vault.lua

While walking around with the animal_dm mod enabled, I sometimes get a
Lua crash, stack traceback is listed below. I've had it multiple times
but I'm not sure how to reproduce it to debug this.
