I originally sent a ticket to FFXIV Game Masters directly regarding this topic but I was basically told to make a forum post about it instead. What I'm saying here is not the original message (I don't have it anymore and it wasn't in the email they sent out to me) but it has the same information and context that the original message does. Names of those involved will not be listed for obvious reasons.
Backstory: Roughly around this time last year I was having significant and lasting issues with my ISP blocking my PC and phone from accessing the internet entirely, limiting my abilities to play the game. At the time I owned a private FC that only contained myself and 2 inactive alt characters (those characters haven't been used in over 2 years), a Free Company house, and a Private Estate. I was unsure about whether the ISP issues would continue and I didn't want to risk losing my private estate to auto-demo as it was my favorite plot in the game and it was also fully decorated, so I decided to demolish the free company house (I used it as a GPOSE studio, so it wasn't a major loss) and make my private house the new free company house. A friend of mine also temporarily joined the Free Company and held the lead role of the company while I tried to figure out the problems with my ISP, and having them as lead role would also mean I wouldn't have to login to have the FC house not auto-demo, that could be done by them.
Things got problematic when the ISP issues continued for a few months and the friend no longer wanted to watch over the estate/house, as they wanted to rejoin some friends of theirs. We agreed that they would hand over ownership of the FC back to me, and the FC house being auto-demo'd was an unfortunate circumstance that couldn't exactly be prevented.
Fast forward many months later and I've since been able to start playing the game again (the ISP issues were resolved earlier than this month, but I had no intention of re-installing the game, paying for a sub and the new expansion when none of the content in the game at the time interested me), but when I logged on for the first time since originally dropping the game back in March, I was not in my FC. I've checked the Lodestone for it and found no signs of it existing on the server either.
My only immediate question is this: Is it possible for Free Companies to auto-delete if there are no active members for elongated periods of time? At most this FC was completely inactive for around 8 months at most. I'd simply move on but a lot of time and effort was put into building up the company, not to mention the Free Company Chest was loaded with materia, dyes, and other materials as I used it as extra storage. In total, the amount of materials in the Free Company chest is valued at around 20mil, and the company itself was probably worth around 10-15mil, so it's a pretty significant loss. The loss of all the work is whatever, I really just want some closure on the matter.
