Been like this for two weeks now. Levelled the cabal again to see if that would shake it but still stuck. Now have two influence to spend and I have Grandmaster rank. We do have the two perks activated that increase cabal size. When I have the cursor flashing above the perk I want (which isn't crossed out), the Research prompt lights up as if I can select it. When I press X to select it the prompt on the bottom left reacts but the perk does not get selected. We can complete cabal objectives no problem and I promote/kick members from the cabal ok. Also seem to have problems right now modifying the cabal description and opening recruiting again. Same sort of issue, I can't apply changes but the buttons do react, they just don't do anything. (Cabal is **Ordo.Calus** on PS4)
