Other than the red blobs for Elohim, I'm also having the following issues with them:
-Elohim towns are invisible (Cottages, villages, and hamlets are fine - just towns are buggy)
-Mage Guild doesn't show up in the new list of buildings.
-Adept can build roads and some other improvements, but not mana nodes (ouch).
^ not sure if either of those last two are wider issues.
i still play my elohim über game and didnt had a problem with adepts and building mana nodes (maybe its because i fixed the blob issue)...
i also dont have a problem with elohim towns - but i remember i "saw" some invisible buildings (or one building) in the elohim city art in the begining of my game. maybe it was the palace or some other early building but in the middle of the city there was a huge emty place.
