"Newbie Bug Fixed
That's right! Today I finally found the source of the newbie bug and squished it. Apparently, there was a missing ] in one of the new saved fields. This missing character would cause files to be saved with a line containing syntax errors, throwing the server off on next access. This field was added in the same patch as the fast-swing fix, so that's why it appeared the fast-swing fix was to blame. I'll update the server with PCRPG v3.16 momentarily."
