WorldSpatial::removePosition() error on world_quit in Unigine 2.6.1

[namal.bambarasinghe]

I get the following error on 'world_quit'. What could be the issue?

---------------------------
Microsoft Visual C++ Runtime Library

Assertion failed!

Expression: positions.find(position) != positions.end() && "WorldSpatial::removePosition(): can't find position"

Hi Namal,

Asserts are disabled in the release build, so if you don't see any unexpected behavior here it would mean some internal engine bug. However, without seeing the actual scene (code + content) it's not possible to say what is causing it.

Maybe this bug was already fixed, but we would be able to say only after a debugging. If you will have some spare time to prepare a test scene for this - it would help a lot.

Thanks!
