Not sure if this is known...
Create Magic Tattoo spell does not work on either server when a familiar is summoned. It seems to have something to do with the dialogue box where when you choose what magic you want the tattoo to hold, it is being canceled out when you're getting the message that you've initiated share spell with your familiar.

There is a temporary workround for this.
You order the familiar to stay where it is and move away to a spot where it will take a short while to reach you. Cast it CMT spell and quickly select the right option before the familiar arrives as it will race towards you. If it's far enough away to begin with you can manage to cast the spell before it arrives.

Thank you, NastyNas!

Also note that when you have more than one CMT spell ready, you can use the workaround for the first casting, then cast the other ones without problems. This is because the familiar will remain in a state of "awaiting dialog" (or something!) and will not fire the share spell script at all. This however means you cannot share ANY spell when the familiar is in that state! The fix to this is to start a dialog with the familiar.
The workaround order would then be:
1) move the familiar distant enough to be able to cast the first CMT;
2) cast the first CMT quickly, then the other CMT as you want;
3) talk with the familiar;
4) cast all the other spells, which will then be shared as usual.
