Summons/Animal Companion hostility

[WanderingPoet]

Animal companions (and summons) have started becoming hostile from AoE spells again. Situation reports:

Cast Grease/Cloud of Bewilderment which hit a druid (immune) and his Ancient Water Elemental(immune)/Panther companion. They began to attack my character and continued to chase even while not in the cloud/grease until unsummoned.

Later the panther which had been unsummoned and later resummoned. Several minutes later along an enemy free road the panther ran over and attacked me

Later I cast Gust of Wind and it hit a different character in the party but not the panther companion or their druid and the companion sprinted across the battlefield to attack me.
