Not sure if the dev sees these forums but there's a bug in the source code rpyc file. Line 8187. There is a close tag for italics but its open pair does not exist which is throwing an exception:
While processing text tag {/i} in '{b}{i}Leave immediately{/b}{/i}{vspace=5}{color=#009933}{size=25}Virtue +1{/color}{/size}{/i}'.:
Exception: '/i' closes a text tag that isn't open.
Either add a {i} after the size tag or remove the {/i} from the very end
