Allies Corruption Immunity And Spread (ACIAS)

Unlike the earlier counterpart of this mod, VCIAS, which is designed to spread the same attrition immunity and corruption spread that vassals of the WoC receive, this is intended to do the same for alliances. Defensive should work, but military for sure.

This was made specifically by request as it was an easy enough change to make, for use for co-op. If you don't like it because you think it's too easy to spread like that, use VCIAS which at least requires you force them to bend the knee first.

What this should do is extend the immunity to corruption of the Allies type, including untainted, to any allies you might have. This includes if you're the empire and you somehow ally Sylvania. Vlad will become immune, while he's your ally, to land of the living attrition, and you to Undead.

Additionally, all races who didn't already do this get the WoC's corruption spread, again including untainted. So in the above example you would also be pumping every province under Sylvania with 10 untainted (technically -10 Corruption in general, but you know what I mean), while he pumped you with vampiric. This can cause some interesting side effects, take that as you will.

As a purely temporary measure against your allies getting nigh constant rebellions or simply sitting armies in their settlements and not really being anything more than garrisons of settlements that don't give you as much money as you could get yourself (assuming you can get anything from them, which depends on your faction of course), I've given a plus 10 to public order for every kind of corruption spread through the diplo. It'll show up as a Faction effect. This should be exactly enough to counteract the negative from corruption, but does not give them the benefits OF said corruption as if they were that way all along, which is my hope to get to.

Now, this isn't perfect, because I lack the scripting expertise to make something like the Corruption Adaptation mod that would apply to all of the forms of corruption, so Vlad might have some issues with public order if you ally him. I'm going to look into finding someone who can help me with that, but for now, this should be in a functional state.

Last note, while I get that 10 corruption, or untainted, is usually rather easy to overwhelm, keep in mind, this mod is not intended to make you super spread like a virus. If you want to do that, you're free to make a personal version and tweak the setting, it's not super complex if you download RPFM.
