I could agree with all of these, but i had to exclude "/ju having 126.96.36.199 items"
since freebuild only has /ju and not other dimensions such as /items
and fb's main version (at the time i post this is 188.8.131.52), i think theres going to be compatibility issues
Or Cy COULD troubleshoot it by detecting a players version and only allowing specific items from versions they were in
for example, if someone is using 184.108.40.206, and does /ju <insert 1.4.1 item> it would say "Your current version of terraria does not have this item."
But yeah overall, these suggestions should be made.
