Absolutely Fuming on some bugs.

Firstly the injury bug. If one of my starting players gets a minor injury, and I make the choice to substitute him, he shouldn’t be coming back into the game. Just had my starting RG get injured in the 1st quarter of a playoff game, I substitute him cause I have depth and I need him should I make it further in the playoffs. What happens? He comes back several plays later ONLY TO GET AN EVEN BIGGER INJURY THAT TAKES HIM OUT OF THE REST OF THE SEASON. 

Secondly, in my dynasty I am a CEO. I have several of the abilities and I had just recently bought the gasoline perk where players start hot in big games. I was super excited to use this perk in the playoffs only for it to not work so now I have to actually get them hot normally so I’m fuming that I wasted the cp on buying an expensive ability for no reason. 
 
please help EA. I have a dynasty with the boys and this stuff keeps happening to all of us.
