Contracts Remastered

RDR2 Contracts mod is back with a remastered version, including new mechanics, improved and dynamic mission scenarios and a lot of other features!
For those who are not familiar, RDR2 Contracts is a mod adding infinite, randomly generated assassination missions that you can pick up from npcs in the game's major towns. These missions has different scenarios, settings and targets and will reward you with cash.
Installation
LML and ScriptHook and required for this mod to work.
Download the mod and extract the zip file.
Place the Contracts.asi and Contracts folder in the game main folder and install the lml mod.
Targets facial composite
A completely unique system which generates a card with the contract's target facial composite.
This new mechanism opens a door for a much more immersive experience. You will now have to actually recognize the target yourself, with as little help as possible.
As for the current version, you can reopen a contract's card while you're in the mission area by holding V.
Dynamic, interactive missions
With the remastered version, missions now have much more dynamic and lively scenarios. Npcs will blend in the environment, which can be used for your advantage. For example: in some cases you'll be able to threaten your target with a new Hostages feature. I won't spill the beans with other examples, you can see for yourself!
Bug fixes, enhancements and performance improvements
There are too many fixes and small enhancements for me to remember, to be honest, but here's a small list:
Mission sets are created before entering their area, to create a more immersive feeling.
AI has been improved.
Custom configurations and translation to other languages are now possible.
