RFP 4.1.4 - MiniPlaceholders 2.3.0

[Tacu56]

[connor33341]

[Adioc14]

found a fix

please do share!

well i only got it to load in 1.21.4 but i tired to see, it doesn't spawn the bots
it says it doesnt show any signs of live or failing to connect/disconnect

i digged deeper that the owner needs to adapt mcprotocollib from 1.21.1 to 1.21.4 because its changed

from start that causing org.geysermc.mcprotocollib error thing is because in new version of protocollib 1.21.4 they changed directories and some of things causing the referencing to be incompatable

what i did is to make the dependency MCBotlib to use mcprotocollib 1.21.1 it made it load but didnt work as 1.21.1 is not compatable with 1.21.4 so no bots or fake players spawn

so real issue is from MCBotlib the owner needs to fix references to match 1.21.4 mcprotcollib to work

and a small fix in RFP to adapt the removal of ymal commands to adapt new version of paper 1.21.4 where no longer supports commands in ymal

sooo only solution is downgrade ur server to 1.21.1 i did that there are downgrade tools that can help you if ur worried
but plugins may break so test them first
