Wall of Fire

[Void]

This is an old problem, but it hasn't been fixed yet.

Basically if the party is using summons, then any summon stepping into friendly wall of fire treats wall of fire as hostile spell and tries to attack the caster of wall of fire.

It probably needs to be fixed the same way as Darkness spell, which is treated as non-hostile.

With the new changes to the Darkness spell, would be great to have this addressed at some point.
