spam error messages in server console

I have the plugin running on my server but I see a lot of error spam on the console:

"Failed to call hook 'OnEntityMounted' on plugin 'CAltimeter v1.0.2' (NullReferenceException: Object reference not set to an instance of an object) at Oxide.Plugins.CAltimeter.OnEntityMounted (BaseMountable entity, BasePlayer player) [0x00019] in <96d3b0315cbc44a7a83c7f983f643c53>:0 at Oxide.Plugins.CAltimeter.DirectCallHook (System.String name, System.Object& ret, System.Object[] args) [0x00235] in <96d3b0315cbc44a7a83c7f983f643c53>:0 at Oxide.Plugins.CSharpPlugin.InvokeMethod (Oxide.Core.Plugins.HookMethod method, System.Object[] args) [0x00079] in <3606d2af539c45e4b5c61658e6a8b307>:0 at Oxide.Core.Plugins.CSPlugin.OnCallHook (System.String name, System.Object[] args) [0x000d8] in :0 at Oxide.Core.Plugins.Plugin.CallHook (System.String hook, System.Object[] args) [0x00060] in :0"

When you start server ? Or other ?

It happens every time you restart the plugin and sometimes when using a heli. Tomorrow, during the restart I will see if it also happens at that time

Changed Status from Work in Progress to Pending

It's strange that I don't have any bugs. Didn't you make any changes in the plugin?

No, I have not modified anything in the plugin ...
I will follow the problem and I will inform you.

We have found a bug or malfunction: When you go on the heli and open the map, you cannot move it.

I cannot report it separately because I have an open report. Sorry for the disturbances.

I fix tomorow
