Whenever creating a custom ideoligion, it seems that all ideograms are available for selection, regardless of the origin of the ideogram or the origin of the ideoligion. It seems that ideograms should either all be available, or the text "unlocked by..." should be removed from the tooltip. Frankly, in my opinion, there isn't enough variety in ideograms, especially considering that these are just geometric symbols and any tradition could adopt any random geometric pattern. I vote that all ideograms remain available and the tooltip text simply get fixed.
To recreate:
1) Start a new colony
2) Create a custom Ideoligion
3) Select any origin
4) Add Ideogram Building
5) Edit the building. All ideograms are available for selection, regardless of current origin, even though the tooltip for some ideograms says "unlocked by <origin>".
