Enigmatic legacy's Angel spellstone equipped, while trying to use Airy Protection tome in offhand crashes servers when both actuate at the same time

This appears to be the crash report on the server side: https://gist.github.com/belathus/3352c0bc34bd72985c10e15482dbe5c9

There is a second crash 1 minute later due to the Server Watchdog.

A fix has been attempted in version 1.5. Sorry for the wait.
