NullReferenceException

Hello,
I would like to report a new issue that has started occurring on the server.

We are receiving a large amount of the following error:

[ERRO] Unhandled error occurred (NullReferenceException)
  at BaseEntity.NetworkPositionTick ()
  at InvokeHandlerBase`1[T].DoTick ()
  at InvokeHandlerBase`1[T].LateUpdate ()

After this error began appearing, we started experiencing several gameplay issues, such as:

Crafted items not appearing immediately

Unable to chop trees

Various actions becoming delayed or unresponsive

It seems that a broken entity or an invalid link on the map may be causing this behavior.
Could you please check if there is any problematic object or structure in the affected area?

Thank you for your assistance.

Hi, your description sounds more like a plugin issue than a map issue.

Before switching to this map, it was a 4500-sized map and was functioning normally.

Changing the map may affect the operation of plugins, I advise you to check the map on a clean server and I am sure that there will be no problems.. I have already dealt with such a problem and the problem turned out to be in the plugin, updating the plugin solved everything

Thank you for your reply.

It seems UnderwaterGuard.cs was the cause.

Thank you for your advice.
