Problem with checking deck for held card. C++ - c++

Question

I'm very new and attempting to create a deck that will be filled at random from cardpool, permterm will also be filled with the same cards. This will give you duplicates of some cards and singles of others, as intended. Then you can use a card or draw a card and it will sort hand() and deckArr() correctly.
The problem comes when you draw and use a card back to back. When a card is in your hand, the corresponding trigger in cardActivation will turn to 1. (Meaning it's in your hand and cannot be drawn again) So if you draw, it handles the activation for that one card and shifts the deck accordingly. If you use the card, it is the opposite. It will turn the trigger to 0 (Meaning its available to draw and inside the deck) and shift the hand accordingly.
It seems that it randomly decides not to run the if statement within draw() [if (cardActivation[x] == 0 && hand[handSize-1] == permterm[x])] and will not trigger the activation, thus throwing off the rest of the program, but the next iteration of the loop correctly runs the if statement. When I get to the end of all the testing the activation is off by 1 because of the one time it missed the if statement. (There should be nine 1s instead of eight.)
I've fiddled and changed my code 100000 times but can't figure out why randomly it decided to skip the if statement, as far as I can tell it should still be true.
I've left my notes and tests within my code so hopefully it can help others understand my thinking process, sorry it's such a mess. It was MUCH cleaner before I started bug fixing. The HP bar information can be ignored, it's apart of something else. Hopefully I explained well enough for some help, I'm losing my mind. Thank you in advance!
