I'm also having this exact same issue, even though I downloaded the latest version of this plugin and Left 4 Downtown (the no-playerslot version). I changed Nick's preferences so he never picks up assault rifles, but when I drop an AR near me to bait him, he still goes to pick it up.

Here are the mods that I have enabled:

Can someone update this please

This seems to require a lot of changes to modify all the arrays from storing entity indexes and use entity references instead which is what should be done to accurately identify the correct entity to affect. Entity indexes are recycled, so you can't guarantee they're the same entity when storing their index. This has been expressed endlessly over the years.

A very complex and heavy plugin for the server, as I understand it, the weapon is forcibly issued to the bot from the ground? Maybe there are some other ways to explain to bots what kind of weapons to take?

[Silvers]

L4D2_OnFindScavengeItem is what bots use to select weapons. Looking through the plugin it is very heavy on the server, lots of strings constantly being created even if they're never used (created before checking IsValidEntity for example). There are lots of string checks that should happen after checking for a valid handle and plenty other optimizations. Could do with being re-written in all honesty and with a lot less code.

I thought it was a fine plugin for the time it came out as it allowed you to prevent the bots from picking up snipers or at the time restoring the original weapon preference for the L4D1 crew before that got fixed in the TLS update.

Nowadays I probably wouldn't use it.

Is there any updates on this? This plugin is a must have

Looking back at the code, it really is very painful, this was probably the first huge plugin of this kind that I ever undertook without really fully having the necessary experience (or skills to be honest), I say it's a miracle it even worked as it did.

It definitely needs a complete overhaul and rewrite, I'm surprised there does not exist a (better written) alternative all these years later.
