How to make Unit changes correctly (Inheritance)
If you want to make changes to a unit's gear, name or any other setting you have two options Both are solid options but have different impact.
If you duplicate to "GlobaclConflictsMissions" This makes a local copy of the prefab. Any updates made to the original prefab in GlobalConflictsUnits will not be updated on your duplicated version.
Please move it so it's under "GlobalConflictsMissions/worlds/[YourName]/[MissionName]"
This is great if you want to have 100% control, but it also means that if something breaks and the dev of the unit fixes the problem. Only missions that use Inherit will be fixed. You will be required to update your mission.
If the Inherit option is not available, see the guide below to add it.
If you Inherit, a "reference" is created that you can have local. It will only contain the changes that you make to the unit. This means that if a change is made to the prefab in GlobalConflictsUnits, your local Prefab will also inherit that change. This is great when you just want to make small changes and is the recommended way to work.
Please move it so it's under "GlobalConflictsMissions/worlds/[YourName]/[MissionName]/Prefabs/Groups or Characters" If it's a change you want to use in multiple missions, feel free to add a Prefab folder under /[YourName]/ for easier organisation
