V0.054 Update Announcement — Snt计划 Steam update #3689767

The enhancement screen now explains that with valid protection, protection materials are preserved on success and consumed on failure while keeping the current enhancement level. Default and key-based gift-box openings now use the same formal single-layer probability rules. This fixes the “Use failed” regression caused by mismatched rule fields, without consuming boxes or keys on failure. Sponsor Monthly Card pet-egg benefits now finish in eight days: one egg per day on days 1–7, then three eggs in one mail on day 8, ten total. Active cards continue from each card's delivered count until ten eggs have been sent.
