Crash on casting spell

Version 0.0.14, Windows 7

Crash happened after trying to cast Chain Lightning on a Wyvern Sonicscreecher. I’ve had at least one more crash on spell cast as well, and it may have been the same monster.

win 0.0.14, same error wher I casted ‘spell strike’ targeting Wyvern Sonicscreecher
