i can confirm that player invincible does not work in newest trainer.
Same problem here !
I can also confirm that option 1 (Player Units Invincible) is not working, also I discovered that if you have option 2 (Carnage Mode) turned on you cannot use option 5 (Buying Buildings or Units doesn't Decrease Resources) the buildings will not be created but if you turn option 2 off option 5 will work as intended. I don't know about options 3 (AI Units Invincible) or option 4 (Game Updates Give Max Resources) I don't use those 2 options.
I'm going to file a report for an update I would like to see 2 other people do the same so we can get this fixed.
This is a pretty cool game!
Ready ! need 1 more
