Engine Alternator producing EC even when turned off

[minkar81002]

Hello. I've noticed that my liquid-fueled engines with alternators are producing Electric Charge even when turned off. Specifically, they are producing the rate of EC/second determined by whatever throttle position was last used when the engine was turned off. So by pressing Z to turn the throttle to 100%, and then pressing X to cut the throttle to 0%, the engine will produce its maximum amount of alternator EC. Pressing Shift and then Ctrl to gradually turn up and down the throttle will produce a minimal but non-zero amount of EC / second after the engine is cut off. Power is generator from the alternator even when the right-click menu is used to shut down the engine.

Is this is a known issue for any major mods?

Here is my mod list:

If I had to guess, maybe MKS or Reviva are causing this, as they change quite a few things about the game.

I have determined that this is a visual bug present in the stock game (1.12.3, at least). The right-click menu will visually show that there is EC being produced, but this is purely visual; the resources are not affected.

The reason I found this bug is because I was using the analog-style Mk1 Lander Can IVA. This has a meter where you can see how much charge is being produced, and this mod apparently reads the same amount which is shown in the right-click menu of rocket engines with alternators.

Seeing as how this is a stock bug, I guess that maybe this should be moved to the unmodded forum. At any rate, at least I've documented it here, in case anybody does an Internet search and has the same problem.
