I've been doing this instance for a while, and this message has been bugging me. It is not a bug, but it is a serious grammar/placement mistake.
"japinpt" is the name of the party, while "kazuya Zinn" and "Japin Hellgate" are usernames. Rephrasing it is not difficult...
"$name", a member of the party "$party" entered Sara's Memory
Change $name and $party for whatever the variable in iRO is.
I know it won't be a priority, but since fixing this is extra-easy, I hope it will get done... sometime.
Thanks.
