Syndicate Intelligence from Interrogation bugged with scarab

I interrogated Elreon, rank 3 leader of Intervention, with the scarab of intelligence, which said +40 or so intelligence per turn. I finished the map and checked progress, to find that Elreon is had given 16 intelligence from 2 turns, and is giving 8 intelligence for the third turn.

When he was sent to interrogation, the safehouse had 0 intelligence, and the scarab was active on the map. I have used the scarab before and not had this issue; may be caused by 1 member granting more than 100 intel, no clue.

+1, encountered same issue. It wasted 1 "quick generating" mastermind run.
