Confirmed with logs/in-game that the prior one was wrong (and thus
always returning false) and current one is correct.

 # Playerbots Module
-`mod-playerbots` is an [AzerothCore](https://www.azerothcore.org/) module that adds player-like bots to a server. The project is based off [IKE3's Playerbots](https://github.com/ike3/mangosbot) and requires a custom branch of AzerothCore to compile and run: [mod-playerbots/azerothcore-wotlk/tree/Playerbot](https://github.com/mod-playerbots/azerothcore-wotlk/tree/Playerbot).
+`mod-playerbots` is an [AzerothCore](https://www.azerothcore.org/) module that adds player-like bots to a server. The project is based off [IKE3's Playerbots](https://github.com/ike3/mangosbot).
 
 Features include:
 
-- The ability to log in alt characters as bots, allowing players to interact with their other characters, form parties, level up, and more;
-- Random bots that wander through the world, complete quests, and otherwise behave like players, simulating the MMO experience;
-- Bots capable of running most raids and battlegrounds;
-- Highly configurable settings to define how bots behave;
-- Excellent performance, even when running thousands of bots.

-## Frequently Asked Questions
+Bots are controlled via chat commands. For larger bot groups, this can be cumbersome. Because of this, community members have developed client AddOns to allow controlling bots through the in-game UI. We recommend you check out their projects listed in the [AddOns and Submodules](https://github.com/mod-playerbots/mod-playerbots/wiki/Playerbot-Addons-and-Sub%E2%80%90Modules) page.
 
-- **Why aren't my bots casting spells?** Please make sure that the necessary English DBC file (enUS) is present.
-- **What platforms are supported?** We support Ubuntu, Windows, and macOS. Other Linux distros may work, but will not receive support.
-- **Why isn't my source compiling?** Please ensure that you are compiling with the required [custom branch of AzerothCore](https://github.com/mod-playerbots/azerothcore-wotlk/tree/Playerbot). Additionally, please [check the build status of our CI](https://github.com/mod-playerbots/mod-playerbots/actions). If the latest build is failing, rever to the last successful commit until we address the issue.
