Observed behaviour

Casting Pocket Library immediately crashed a Single-player game. Hesitant to use on a Server with concern about crashing it.

Tried 3 times with same results.

Notable results from Crashlog:

GL info: ERROR RuntimeException: No OpenGL context found in the current thread.

Expected behaviour

I expected the Pocket Library to work in both single-player and server environments.

Steps to reproduce

1. Start single-player
2. Equip full set of generic Sage Robes and Sage tome with Pocket Library
3. Cast Pocket Library

This happened with both the Master Fire Sage tome and the Master Healer Sage tome. Haven't tried it with others.

Looked at the 141 bug report and it looks like a similar crash report (ticking player).

Attempted all normal fixes:

1. Made sure video driver was updated and that Minecraft is using graphic card
2. Tried removing Options.txt
3. Updated Java to latest version
4. Downgraded Java to version 8.51

None had any effect. This spell used to work in a older release of Ancient Spellcraft. Later, I may downgrade Ancient Spellcraft to identify the working version.

I'm aware of this, fixed in dev already. Will close the ticket with the commit push.
