EDIT: Forgot to mention that the Saturday's Child obstacle is an issue in Holodeck. My bad.
I can confirm the Saturday's Child obstacle (while escorting the princess). In fact, in my case, it actually halted further progress because she got stuck in the middle of the object in permanent battle with the Klingons (yes, she couldn't die either). Per support's suggestion, I exited and re-entered the instance. The object was still there, but I got lucky and she glitched and went around, and the Klingons followed her out of the object.
