Hello. Regarding conflicts, OnEntityTakeDamage 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 actually submitted a PR today to add support for such hooks.
Hopefully, MrBlue approves my pull request, which removes these persistent conflict messages for hooks where the type doesn’t matter. Plus, it includes a delay between messages to prevent spam.

How often does this error occur? If you have any additional information about when it happens, that would also be helpful.

Changed Status from Pending to Work in Progress

it appears randomly, for example the server works for 6 hours and nothing pops up and suddenly spam
thanks for the quick response I spent a lot of time setting up the server and suddenly something like this, it's good that I can ignore it
