Re: Any way to bring sims from the legacy edition gallery to the original one?
@tommidani Where do you have this sim saved? There's no Gallery for the Legacy Edition, but there is an in-game library, where your sim would be if you'd saved them. The files from that sim can certainly be transferred to the standard version of the game—there's no reason a sim created with an older version shouldn't work in a newer one, and the Legacy Edition is basically just an older version.
When you save a sim to your library, a number of corresponding files are generated in the Tray folder. There are several files per item, so you'll need to get them all. If you're not sure which files go with your sim, just sort by date modified—all files from a given entry will have the same date.
You can move all your Tray items from the LE folder to the normal one, if you want, or just move the files for one particular library entry. In Documents\Electronic Arts, you probably have both a "The Sims 4" folder and a "The Sims 4 Legacy Edition" folder; just copy the Tray files you want from the LE folder to the regular one.
