Btw, the default "PlayerBottomBuffListPlugin" does not have that afaik. I think you added it yourself.
It is not a good idea to change things in default files since those changes will go away next update.
Trying adding this to your "PluginEnablerOrDisablerPlugin.cs" in "User" folder, under the "Customize()" method:
Code:
Hud.RunOnPlugin<PlayerBottomBuffListPlugin>(plugin =>
{
plugin.RuleCalculator.Rules.Add(new BuffRule(483552) {IconIndex = 5, MinimumIconCount = 1, ShowStacks = true, ShowTimeLeft = true }); // Squirts
});
