A question was migrated from Writer.SE to our main site. There it was placed on hold for unclear. I agreed with a comment placed there from Lawrence (from our own community), but when I tried to up-tick it I received a message from the AI:
This comment is not eligible for voting or flagging.
I have never seen this before, so I tried another question (also on hold) and there were no problems.
Anybody know what is going on here? Is it because it was migrated?
