CI 3.1.13 + PHP 7.4 DB error - Smekke - 09-21-2023

So I inherited an older site running CI 3.0.x
I have upgraded CI 3 to the latest version (3.1.13).
Currently running PHP 7.0.33
I'd want to upgrade to PHP 7.4.33 to be at least a little more up-to-date but whenever I do that I get a very random error on the index page.

Code:
Error Number: 1146

Table 'database.A' doesn't exist

SELECT a.* FROM A a WHERE a.`show` = 1 ORDER BY a.A LIMIT 5

Filename: models/Mod_modules.php

Line Number: 1363

It seems to try and perform a select from a random table called 'A'?
Obviously it doesn't exist but I can't really figure out why the change in PHP suddenly results in this bogus query running.

in database.php, my dbprefix = ''. I don't have any prefixes on the tables.

Hoping someone might have an idea.

UPDATE: somehow all of this went away, very weird, but ok.
