🟩 BlackBar Gaming recommends
- Treat Celebration as the start of your post-HQ30 economy, not as downtime. Oil income compounds slowly and rewards early setup.
- Black Market timing has changed across server generations; use the live Celebration menu instead of assuming an older Week 2/Week 3 date.
🟥 Warning
- Some Celebration side-event names and start days have shifted between rollouts. Overlord availability is listed here as Season 2 Day 89. For other side events, follow the live event timer if it differs.
