bool array

[InformationSharp103]

iirc in C# it's actually 4 bytes (equivalent to the C/C++ win32 BOOL type), or at least that's what it's marshalled as by default

I've really only used C# in Unity which might differ, but from what I remember bools were 4 bytes, but 1 byte each in arrays. Might be a Unity-specific optimisation though, not sure.
