Ok going to take very quick stabs at these but keep in mind I haven't
had sleep in about 40 hours or so now...

Are you by chance inserting the plugin on a bus instead of a track?
Busses do not have any delay compensation.

WAV32 has a file size limitation, though I am surprised you got to 5G
in that case. This is a known issue in the file format as it only
uses a 32 bit signed INT for addressing purposes in it's header, and
as a result can only store so large of a number.
