hey, i need to make an upgrade which has 3 levels, first level is purchase, second level is use, third level is unuse. What this means is that after the player has purchased it, he can choose to use it or not use it this round. It cost to purchase it but its suppose to be free to use or unuse. However, from what i have experienced, i can't make an upgrade that cost less as the levels go up. Is there another way? i can also not find a trigger that adds a new tech as if there was, i could add new tech after player has purchased and it could cost $0.
Anyways, thanks in advanace
