Engine turn off on action group

[Mine_Turtle]

My engines keep turning off after a short period, if they are turned on using an action group. It does not matter which action is used: toggle or activate. The problem does not occur, if engine is activated manually via the right click menu.

The problem does not happen on newly spawned vessel on launchpad, but on the one built via EL shipyard in orbit. I have tried disabling MJ and TCA(in game) but it does not affect engines. 

Game log does not reveal anything either(except a lot of FAR exceptions, but thats unrelated):https://drive.google.com/file/d/1_u_PyZjr3ypq25UekqxG7rtjBtkGo29m

It was TCA smart engine setting messing with my engines. Even when TCA was disabled as a module it still had control over engines. Disabling smart engines solved the problem.

Oh yeh, I can never get smart engines to work sensibly.  I just have different engines on hot keys and do it manually.
