When you see this FPP error, it means that FPP (Falco's Prop Protection), a system that comes with DarkRP, is stopping you from tool-gunning the entity. This can be easily fixed with some minor in-game config edits. The following guide will walk you through how to fix it:
- Open the spawnlist menu (Q menu)
- On the right hand side, navigate to Utilities
- Head down to Falco's prop protection -> Admin settings
- Expand Toolgun options
- Enable Admins can use tool on world entities and Admins can use tool on blocked entities.
- You should now be able to toolgun the entity and remove it.
