hello guys ,
i am aware of the issue (Tupolev has informed me) and all these are caused becuased i included in the release files, the sim.cfg values from test files and not from the final one. this is the result when i am rushing releases

but anyway ,thanks to Tupolev ,the issue is cleared up now.
later today , i will reupload the MEP v4 ( now it will be v4.1 ).
at this version, i eliminated the 'flying ships' effect .
also, i reworked the look of ships very far away at visual limits (at the following pics the 'ShipVanishingHull' option -which also is reworked- is not enabled )
ship close to visual limit (ship is with light colors painted):
ship at about 15km distance:
