Linux HELP! Leo doesn't show up at Feast of the Winter Star

[Kedamono]

Got Leo as my secret villager for the gift exchange, but he doesn't show up at the Feast next to Linus, Or anywhere. How can I do the gift exchange now?
The Stardew Valley Wiki didn't give me much help either, unfortunately. Never used any mods and haven't used any cheats or glitches in this save file.

How many hearts do you have with Leo?

There was a bug where you could get him as your gift receiver before he actually joined the festival (6 hearts are necessary). But it should have been fixed in 1.5.1.

You can just leave the festival without giving gifts to progress your game.

I think the bug that was fixed in 1.5.1 was Leo being the one selected to give you a gift, not Leo being the one you give a gift to.
