This is a simple patch operation that changes the opinion from being harmed from your own colonists from -15 to 0. This should prevent your colonists from hating each other because of accidental friendly fire. But as a consequence, also things like social fights.

Created for my own personal use. Its not perfect, but its better than disabling Friendly Fire as a whole. Maybe someone else will enjoy it.
