Added a SQL query dump on 7.2 to visualize the error next time, let me know if it happens again

Hi,
what can I do to fix it? and what about the first error?
Regards.

Do any of your world names have 's by any chance?

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 's'' at line

Looks like the apostrophe in the 's is messing it up. Most likely not escaping the quotes for some variable (Helper.escapeQuotes()) in one of the delete functions in the StorageManager

Here you can see all worlds that I have: http://mine.mc-evolution.it:8123/

I could not locate the issue in a code review, but I did clean up the code in question, after which I went through and named fields with 's allowed players with 's and I can't reproduce this issue. Will release soon.

In which version will be fixed that?
Regards.
