I have 2 questions with this plugin.
1. We also have a plugin called VehicleDeployedLocks that can add a lock to any transportation. However, it wont let us add a lock to the horses in this plugin. Is there a change that can remedy this?
2. If there is anything in the horses inventory when a player hits it with the hammer to pick it up, all the inventory is lost. Is there a way to have it drop as a satchel or automatically add to players inventory?
Thank you in advance.

Why is Vehicle Deployed Locks prohibiting locking the horse? Does it print a reason in chat? I'm guessing it's related to ownership, for which there are config options you can change in Vehicle Deployed Locks.

This plugin does not currently implement any persistence for picked up vehicles, so things like inventory, health and module configuration are lost. It's something that can be improved in the future. For example, pickup could be disallowed if the vehicle has items/fuel or isn't at full health. That would solve multiple problems, and then some additional logic could be added to store things like car modules or horse breed. The extra info could possibly be stored in sub items of the vehicle item, so that they could be saved across restarts for free.

I was told by my partner that the horses will indeed now take a lock. I forgot she had told me. Sad to see there isnt a config or check to save players inventory. perhaps that can be worked on. Thank you.
