Not sure what the proper way to ensure it matches the C++
layout here, but at least it seems to be mostly working for
now. Thanks again!
Ugh what GetIntPtr? Unless of course this header file is
wrong[0].
Make the members match exactly, order and everything and it
should "just work".

Woops, that GetIntPtr came from the .cs header in the same folder
as the C++ headers distributed with the SDK, that'll teach me to
ctrl+f "class ISteamClient" in all open files and copy/paste
before reading.
Anyway I played around with it some more and found the one single
line that was causing the problem. It needs this:
HSteamPipe SteamAPI_GetHSteamPipe();
rather than one of these:
HSteamPipe SteamAPI_ISteamClient_CreateSteamPipe(ISteamClient
instancePtr);
virtual HSteamPipe CreateSteamPipe() = 0;
It looks like the pipe is already created upon initializing and
calling CreateSteamPipe creates a secondary one that doesn't
receive callbacks. SteamAPI_GetHSteamPipe is called inline to
retrieve the current pipe on initialization of the the classed
version of the API, but the documentation doesn't mention it
exists at all, leading to confusion when using the flat version.
Well, mystery solved.
