I noticed today when using the trainer that the unlimited energy not only effected the player but also the enemy tech (it was a funny 30 minute stand off before I realised).
Is this a bug that has developed with the slight version increments or has this always been the effect?
Yes, I noticed this as well, I was sitting there and I'm like why aren't you dead yet?
As the game was updated on March 16 to v0.7.4 it is likely that the trainer needs to be updated.
Please use the update notification system to report a game patch, update or to report that the trainer may not be working with the latest version of the game.

Keep in mind that it needs at least 3 reports until the trainer gets reviewed.
Since its still in Early Access and always getting new features, I'm not too worried if the trainer is updated on a regular basis.
Also, the past several versions of the trainer have not worked perfectly anyways. The infinite fuel is often broken, as is the Disable Enemy AI feature.
Trainer crashes my game when loading a saved game, works fine when starting a new game though. Anyone else having this problem, or know of a way to fix this? Seems like the save game is getting corrupted from the trainer.
As this game is still in the 'fiddling around with stuff and rewrite code because devs are too stupid to make it work in the first place' phase aka Early Access it is always a risk to use a trainer which alters game code that is possible to change anyways.
Please ask the game devs when you get a full working release that you paid for and that there is no fun or adventure in it to watch them breaking your save games.
