[Reg] Override environment feature (param "E") isn't working

Hi,

after couple of scripts and some debugging I've realized, that the "E parameter" in automation/command line isn't working correctly.
So I checked this in SoapUI, in the "Launch TestRunner" feature and it looks like I was right, there is a problem in setting/overriding the environment while using TestRunner or using SoapUI in automating the tests (with NAnt scripts).

I attached some simple script to verify this.
In this attached project, I set some active environment (it doesn't matter if it was in TestSuite or TestCase) and in "Launch TestRunner" I overrided the environment to something else, the environment wasn't changed.

It looks like this functionality is broken since the new 4.6 version and it has a very bad impact for our test framework.
I've tested it in the stable 4.6. version as well as in the latest 4.6.1. Maintenance build and it's happening in Composite and also in non-Composite project and in Project-TestRunner, TestSuite-TestRunner and TestCase-TestRunner too.

Could you, please, investigate this?

Adding specific example with logs (I had to remove some confidential data)
Example: Before the TestRunner, environment "Env1" was set as active, in TestRunner I set the environment "Env2", but as can you see from the logs, the active environment is still environment "Env1", instead of expected environment "Env2"
