(checkmate923) NPC를 공격 불가함 (can't attack the NPC)

[vast oyster]

NPC's invincibility is false
The player cannot attack the NPC.
But NPC attacks players. Also
The rest works fine. The Minecraft version is version 1.8.8.
And I used Sentinel plug-in versions 2.9 and 2.8.
Is there a solution?

Info: 1.8

Minecraft 1.8 is an 10+ year old Minecraft version (released <t:1409643900:R>) that we cannot reliably support.
We maintained support for 9 years, but time has long since run out. We cannot and will not provide support on this Discord or other platforms for it.
You can and should update your server. There are plugins for clientversion support and older-style PvP available.

For more information, refer to https://wiki.citizensnpcs.co/Minecraft_1.8.

I used Custom Spigot
The current version of the server is 1.7 to 1.20.1
Should I fix it by lowering the version of the plug-in

[gray cosmos]

can't do anything to offer support for a custom server based on a 10 year old minecraft version

if you want support, update to latest valid standard server version

if you want to use a hacked up custom thing... recognize that you're creating your own problems and it's your responsibility to find your own solutions, nobody else has the power to help you
