Right now, these are my plans for gachas:
BEAUTY GURU:
Was a 50% donation to MSF. Will rework some content into an omega/BOM makeup set.
KNICKERS
Was a 50% donation to MSF. Will put 4 or 5 favs as copy/mod into the lucky chairs.

Glad you don't have too many things to switch over. This will be a major headache for some creators.

HYGGE

Was 50% donation to ACS. Retiring completely. Play before Aug 31 if you want any of this.
THE THREE WITCHES

Abigail is my favourite, will make her a normal release. The other two skins will be lucky chair'd. The makeup will be retired, so if you want it, play before Aug 31!

Sehra same, I only have 4 active gachas since I regularly phase out old stuff I'm no longer happy with.

ALCHEMY, LADY VENOM, BYZANTINE, FOIL FLASH, SWEET THINGS, COLOUR TREND, and INVERSION were all already retired, no plans to revamp any of them.

Lucky chairs is a good idea
