Operator panel L4 light remains dark

[Rongor]

Playing in 2.7.8.16140 I am currently learning the front seat, doing everything by the book.

On page 54, the official "Mi-24P Quick Start Manual EN.pdf" provided with the module tells us to turn on OBSERVE on the operator panel. Th L3 light should then start to blink and after 10-15 seconds the L4 light should illuminate. Then the ATGM sight doors are expected to be open.

When I do that, the L3 light doesn't exactly blink, it's more like a flickering as if the light bulb has to be replaced. The L4 light never goes on. The sight doors though are opened.

Function of weapons emplyoment was not affected
