So I was playing my Praadera game, where I have Briieth, Andrion and Tael in Twinbrook - with Tael set as Briieth's sister (and also a family Plumbot, because I always do that), and while Tael was busy blowing up objects at the junkyard, my namesake, Mimi Sardinia - who I'd dumped in a swamp house after using her to replant to city garden in a Bigger Builder's Island game - turned up at the front gate of the junkyard, alogn with her pet green dragon.
The sim in the far background is Tael, apparently celebrating her latest explosion - and wearing a really freaky facial expression - while wearing an outfit that she does not actually own. I think it's a game bug somehow. Edit: Not a bug it turns out, it's apparently her career outfit. She's a self-employed gardener.
