For the next release of FSUIPC7, I have added:
INTERACTIVE POINT GOAL at offset 0x341B
INTERACTIVE POINT OPEN at offset 0x3424
both are 1 byte, with each bit indicating the index number (e.g. 0x341B bit 4 is INTERACTIVE POINT GOAL:4).
This won't help your problem at the moment, but if you could log these offsets, as well as offset 0x3367 (EXIT OPEN), all as U8 in hex, this may shed a light on what is being used.
It is possible to spoof the reading of the existing door offset (0x3367 for EXIT OPEN) to these new offsets, but most probably the bits referenced will be for different doors.
I don't have the FSL A321neo, or GSX/SLC, so cannot test with these. I looked at the FSL A321, but that just seems to use the EXIT OPEN offset.
Anyway, maybe try the attached and add the offset logging for those 3 offsets (all as U8 in hex), and we can see what this tells us.
