NullReferenceException and lag

Hi everyone! It's me again! haha I just want to ask if someone know how to fix this or what I can do. I don't know if is for the plugins or not but in my console appears 15 times the same error in less than a minute:
NullReferenceException: Object reference not set to an instance of an object
NullReferenceException: Object reference not set to an instance of an object
NullReferenceException: Object reference not set to an instance of an object
NullReferenceException: Object reference not set to an instance of an object

It's just mad and the users are suffering are horrible lag, I don't know if it's due for this issue or for another thing because I still having the error:
TimeWarning: Net.sv.Cycle took 1.05 seconds (1048ms) ,
TimeWarning: AIHandler.Cycle took 0.95 seconds (948ms) and
Calling kill - but already IsDestroyed!? build/wall (BuildingBlock)


Thanks so much for your help guys!

 

Do any of you get this error message:

Code:

The referenced script on this Behaviour is missing!

What is cosing this? Anyone?

 

What about this one?

Code:

[SV_RPCMessage] playerattack - Exception has been thrown by the target of an invocation.
IndexOutOfRangeException: Array index is out of range.

 

I'm running Oxide Version: 2.0.755, Rust Protocol: 1242

I think I tried to unload all the plugins, and still getting this error in those blocks:

Code:

No fn idea what's going on, and I think it's lagging the server too ...
