Hello, you opened a support ticket regarding the RealPVE plugin in the TwigsDecay plugin.
OnEntityEnter is an On object hook, meaning its return value doesn’t matter for plugins. It's just a warning that can be ignored, it doesn't affect anything, aside from being annoying with console messages. Oxide simply doesn’t account for this when checking for hook conflicts.
I've already found and suggested a solution to this issue, but it needs approval. You can also support this solution to help get it approved faster.
