Explained by me on Discord, 20 February 2020:
"Found a bug that causes characters to load slower based on the number of items in their inventory.
Every item causes a query to be executed in the db. On my local machine,
the specific section of code is now ~40ms faster when loading 1 character full of items.
Here is what I'm referring to:
"AND petid IS NOT NULL"
should be
"AND petid > 0" or something similar
Basically, the petid field is not a boolean. The check will always pass since -1 is not null,
and the number -1 is used to indicate if the item is a pet or not."
