-/*
-Ares has a hook at 0x4571E0 (the beginning of BuildingClass::Infiltrate) and completely overwrites the function.
-Our logic has to be executed at the end (0x4575A2). The hook there assumes that registers have the exact content
-they had in the beginning (when Ares hook started, executed, and jumped) in order to work when Ares logic is used.
-
-However, this will fail if Ares is not involved (either DLL not included or with SpyEffect.Custom=no on BuildingType),
-because by the time we reach our hook, the registers will be different and we'll be reading garbage. That's why
-there is a second hook at 0x45759D, which is only executed when Ares doesn't jump over this function. There,
-we execute our custom logic and then use EAX (which isn't used later, so it's safe to write to it) to "mark"
-that we're done with 0x77777777. This way, when we reach the other hook, we check for this very specific value
-to prevent spy effects from happening twice.
-
-The value itself doesn't matter, it just needs to be unique enough to not be accidentally produced by the game there.
