Just to update you all!

I waited until the last minute as I was really hoping the devs would come up with an answer. The GMs were in touch during the last hour but said they couldn't help, that they couldn't promise any compensation if I relinquished, and that it might not work. And that I had to wait for the devs.

No way I could just let it lapse without trying; I would've always wondered if it would work....and it did! I relinquished my plot in Goblet and was then able to buy the plot in Shirogane as normal. Phew!

Obviously, I've lost out on a few thousand gil but it was absolutely worth it!

I have recorded the whole thing (including showing the bug again and that all my alts have no property) and will upload it asap in case it helps others.

Thanks again to all who tried to help! <3
