Observed behaviour

The Farsight spell does not work (no zoom effect) when Simple Core API library mod is installed

Simple Core API mod

Expected behaviour

I expected the Farsight spell to work with Simple Core API library mod.

Steps to reproduce

1. Add Simple Core API library mod to a server (along with Electroblob's Wizardry and Ancient Spellcraft mods, no need for Simple Ores mod)
2. Join the Server
3. Cast the Farsight spell (notice its lack of success)
4. Close the Server
5. Remove the Simple Core API Lbrary mod and repeat Steps 2-3 (note the spell working)

Note that other users have reported a similar issue with AbyssalCraft.
