I am having the same issue as the original post. We have a small FC and really have no reason to upgrade house size but we decided we wanted to and raised the money, realizing that one player who wasnt on since before 2.2 but came started again for patch 2.3.... he joined because we hunted together on first day and it seemed like a no brainer for a small FC, but now his stabled chocobo has been holding us up for a week, and im sure if he knew he would have no problem removing, but seems kind of silly that the whole FC must suffer, maybe even install like an inactive timer where it would unstable after a week, this way no one can just have a lvl'd chocobo without playing anyway? i hope they fix soon though my house we picked out may sell any day!
