Probably, your villagers were sick initially, but once they were "healed", they became "weakened." At that point, they will want to Go Indoors, because they are not technically sick.

I understand that you can load your last hotsync'ed Villagesavegame.pdb file, and start from that point. Mine is located in "C:\program files\palmone\user_name\archive", but I think some are also in the backup (instead of archive) folder.

Find the villagesavegame.pdb file, note the date and time on the file, set your Palm T3 to that same time, double click the villagesavegame.pdb file, do a hotsync, and you should get the old game back.

Good luck!
