我都問過原作者, 佢建議 (Works well on vanilla server. Probably some of the add-ons (custom campaigns) cause the conflict.)
How to delete this mod
You can disable it with convar but plugin will still stimulate part of the vscript which is responsible for collecting cans.
That's why i highly recommend that you delete mod (vpk file and plugin) if you do not use it. Now this work will be to execute through Valve scripts and not via plugin
