Hey unfortunately it's not possible with how construct 2 works. For really big numbers I need to set the number myself via variable in the form of text. Ints in the engine only go up to 10^18, which is such a hassle in an idle game that deals with big numbers. The cost of 1 diamond is 10^21 so I set if gold > diamondCost add 1 diamond etc. Now if you buy varying amounts I either don't know how to solve this or I can't find the solution. If anyone uses construct 2 and knows a solution please pm it. The only other thing I can do at this point is set constant rates, I can add 10k, 100K. Leave a suggestion of which amount you'd like to get.
Hey! We think we found the problem, and we are making a build to fix it. We will release a patch as soon as possible!
