I don't know if this has been reported before, but it seems to me that assets for the druids (e.g. hive druid innates and northern druid beetle animation) are not installed if you choose to skip the sphere part of the mod. I tested on an install of BG:EE with SR and SCS IWD spells installed prior to FnP, and the hive druid would lack animations and icons for the shapeshift innates.
edit: okay even using the sphere system the animations are not there? Strange.. Also, the hive druids "summon spirit spider" in fact summons a snake. Maybe change name of the spell?
Edit 2: It does work on SoD version of BG1 however.
