Is it possible to move the sponge mod Bukkit map to the forge mod Bukkit map?

[hospital_VIP]

If you move the sponge mod Bukkit map to the forge mod Bukkit map,
(missing minecraft entities sponge human)
If you ignore it and run it
I was wearing protective 4444 armor, but I was killed by a magma slime in 2-3 hits.
The expectation is that the user entity is either removed or not recognized, so it ignores the armor.
Can you please help?

do you use forge or spigot/bukkit, or what are you talking about?

위조 나 spigot / bukkit을 사용합니까, 또는 당신은 무엇에 대해 얘기하고 있습니까?

At first, I put a sponge in the forge and used it
I'm trying to change to Cat Server, but it shows up in the console below
