Max clubs per sim

I'm trying to increase the max clubs per sim.

I've modified the value in the Python script (clubs.club_tuning.ClubTunables). I've found it in the following GFX ressources too :


But the cap stay the same in the UI in game (in the Sim club panel, or when hovering the Join button in the Clubs management panel). I'm not that sure I'm modifying the GFX ressources correctly (using JPEXS for that, but I'm not familiar with it).

So I have a couple of questions :
- Is it moddable or is this something hard-coded somewhere ?
- Is there anywhere else I should look at ?

Thanks !
