So I was able to replicate ths issue and have narrowed it down.
A machine shows up in the GUI and I edit the the custom fields tab. This enters it into the CompCustom table (the machine doesn't appear to be entered into that table until you edit it which is an annoyance).
I delete the machine from the GUI console, giving it a 10 minute time out.
The machine is deleted from the Computers table but not the CompCustom table.
When running reports that use the CompCustom table e.g. Last Patched Date, the deleted machine still shows up.
If you drill down into the machine, you get the error below.
So it seems the delete query is not removing the machine from the CompCustom table.
Thoughts?

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.IndexOutOfRangeException: There is no row at position 0.
Source Error:
The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated the error. Example:
<%@ Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your application:
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.
