Unhandled Exception duplicating an entity

Made one MeleeContext_CorpseTrap entity and added position box.
I was trying to save some time by duplicating and then editing the position. I’ve done this before this time I got an unhandled exception. I let it quit and tried again.

It happend a 2nd time too.
This is with the Staging 0.9.3.42 update pushed earlier. This is also Steam. version.

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

I’ve changed quite a lot of backend stuff recently - seems like I overlooked my swap to using system numerics instead of my own Vector format for serializing.

Thanks for the report - I’ll try get a fix out later!

[MattFiler]

This should now be fixed in the staging branch.
