With or without mods, setting "this enableStamina false" messes up crosshair alignment depending on what unit is played. For example, this affects the Blufor "Ammo Bearer" but not the "Rifleman" units. I have not tested with any other units, but I suspect it has something to do with the unit's loadouts.
Here is a screenshot album to illustrate the bug. I will create a feedback ticket regarding this. http://imgur.com/a/hFTdO
1: Start game with or without mods.
2: Open Eden Editor
3: Place Blufor Ammo Bearer unit
4: set "this enableStamina false" in unit's init field.
5: Play as placed ammo-bearer
6: Aim down sights and they should be mis-aligned.
7: Return to Eden Editor, and set "this enableStamina true" in unit's init field and play now.
8: Aim down sights, and they should be aligned correctly.
Alternatively,
1: Start game with or without mods.
2: Open Eden Editor
3: Place Blufor Rifleman unit
4: set "this enableStamina false" in unit's init field.
5: Play as placed Rifleman
6: Aim down sights and they are alligned correctly.
I tried this with such as CBA/ACE3, and without any mods loaded. There may be a difference between 2d and 3d editor, I have not had a chance to test yet.
