Softlock with sigil interaction:

[mallardj]

When a card with skeleton horde is played and there is a remnant of haunt sigils on the table that applies to a skeleton, a softlock occurs.

Corresponding exception:

[Error  : Unity Log] InvalidOperationException: Collection was modified; enumeration operation may not execute.
