hello

This is a message board, not a chat room, so there are not always people watching, sometimes it can take a while to get a reply.

 

That being said, 1.12 is no longer supported here on these forums, due to how old it is.

Please update to a modern version to receive support.

 

More information on supported versions can be found in the LTS link at the top of every page.
