Crash report

[CharWS]

Describe the bug
Removing army of the dead from prepull actions for frost APL and adjusting another cast to occur when army was previously channeling causes the sim to crash.

To Reproduce
Steps to reproduce the behavior:

1. Open the DK Frost APL
2. Remove Army of the Dead from prepull actions
3. Move a presence swap to occur when army was being channeled previously
4. Sim crashes

Expected behavior
When removed from prepull actions army of the dead should no longer be channeling and shouldn't interfere with other additions
