• Added the "RenaissanceAndBaroque1.18.zip" to the server /resourcepacks.

Error in server logs when loading and no paintings from pack shown in server:

the renaissance and baroque resourcepack seems to be having some issues.
please contact the creator of said resourcepack so they can update their pack !

You could also read trough the latest.log to see what kind of issues the pack has.

the error shown means that it is not recognized as a proper zip file btw
you may want to unpack the contents and make a new zip file out of it. .rar doesnt work

marking this as resolved due to time and lack of response
