Heist quest contract 'Slaver King' doesn't exist

Hello,

I cannot start a quest called "slaver king" because the quest contract for it is missing from my inventory, I have the quest enabled, but I cannot do anything.

How can I solve this?

Edit: I should specify, I did the following to get myself in this situation:
- Talk to quest giver after picking up story contract
- Talk to Adiyah
- Place item in inventory
- have the game crash
- leave because it was late

After that, the quest is permanently stuck to "talk to adiyah to initiate contract", but I cannot do anything there.

Thanks that was it. Strange part is I looked through my heist locker and it was nowhere to be found, now I opened the locker again, searched for it, showed me exactly where it was.
Issue solved.
