Hello,
Thank you so much! Thanks to your report, I was able to identify and fix the issue. The fix will be included in the next update.
Don't worry—you'll automatically receive the Synthesizer Clothing 11 when you launch the updated version. As with every update, you'll just need to copy and paste your GAME_PROGRESS file into the new version, and the game will automatically fix your save.
I'm really sorry about this issue, as I hadn't noticed it before. Feedback like yours is incredibly valuable to me, so thank you again for taking the time to report it.
See you soon! (The next update should be out in 1–2 weeks.)
