Sometimes misses the player's ip

[Zhou-Shilin]

What version of AdvancedBan (/AdvancedBan) are you using?
2.3.0

What kind of server do you have (Bungeecord/single server)?
Single server, Spigot + Forge (Arclight)

What server version (/version) are you using?
arclight 1.18.2 1.0.7

Please provide the EXACT steps required to reproduce the problem...

1. Install the plugin
2. Let some players join in.
3. /banip <name> <reason> -> Sometimes gets There's no saved IP for <name>. (only very very few players' IP is no saved)

Any error/log post it through pastebin.com and link it here. (Also include /plugins/AdvancedBan/logs/latest.log)

Add any additional information below.
I'm not sure if it is because the player is hacking. But I can get the IP by reading the log file, so my server can get the player's IP but Advanced Ban cannot.

Test on a normal Bukkit-based server such as SpigotMC or PaperMC. Using Arclight is likely to cause issues -- with any plugin, not just AdvancedBan.
