-What’s New
Previously: players with high pings weren't able to join the server. - ✅ Now: admins can adjust the kicking delay, giving modsync time to establish connection with the client. Added commands to bypass players. - 🎨 Admin commands — /modsync ignore <player> and /modsync monitor <player>

- Improved client verification timing The server now waits longer before deciding whether a player is running the ModSync client mod. -What’s New
Previously: the verification window was too short, causing false kicks or missed checks if the client took slightly longer to respond. - ✅ Now: the verification delay has been increased, giving the server enough time to properly confirm the client’s presence before enforcing rules.
