Issue

When bot is turned on, if the Check Players option is enabled in the Extras menu of vBot_4.8 (accessed via the vBot Settings and Scripts button for those unfamiliar) and another player appears on the screen, the following errors appears in the terminal:

ERROR: ProtocolGame::parseCreatureHealth: could not get creature with id 268435458

Images

With the Check Players option enabled, when another player appears on the screen, the code in extras.lua, triggered via the onCreatureAppear function, uses g_game.look() and onTextMessage to retrieve the vocation and level of the other player from the server log message, and then :setText() to draw that information over the character.

Expected Behavior

With the Check Players option enabled, when another player appears on the screen, the script should automatically "look" at the player to find out his/her vocation and level and draw it over that character (see image below), with no errors in the terminal.

Environment

Using: Unmodified latest main (commit 262d238)
Client: OpenGL x64 compiled using VS Solution
Operating System: Windows
Server/Protocol: TFS-based 10.41

This does, indeed, fix it for me.
