[23:13:33] [Server thread/INFO]: You may be still using IDs and CrackShotPlus does not work with them
[23:13:33] [Server thread/INFO]: anymore. Try /csp convert command to fix this. If that does not work
[23:13:33] [Server thread/INFO]: you have something else wrong in your configurations.
[23:13:33] [Server thread/INFO]: Note that converting has to be done in older than 1.13 server.
[23:13:33] [Server thread/INFO]: You can not convert in 1.13 server or above.
