CI 4.4.0 modules shared services not working

I assumed your modules are like these:

Code:

Modules/Foo/ ... Module Foo
Modules/Bar/ ... Module Bar

But if you also use `Modules/` as one module:

Code:

Modules/ ... Main Module

You cannot remove the Module path from $psr4.

But it is not recommended. Because it is confusing.

Code:

Modules/Bar/         ... Module Bar
Modules/Config/      ... Config folder in the main Module
Modules/Controllers/ ... Controllers folder in the main Module
Modules/Foo/         ... Module Foo

Correct - each subfolder is as separate module.
I am not using "main module"


Modules/Auth
Modules/Base - this is what i can call CORE of modules, main module
Modules/Cms
Modules/Currency
Modules/Member
Modules/Settings
etc...

So Base has registrar, which connects to DB and tries to use one of Settings model.
While Base is loading, Settings module is not know by the system yet.
This makes Services misleading infinite loop.
I will jump into debuging now. 
Busy with other projects, you know...
