Sent you in PM.
The same result is the second time. The contract with my address does not work.
I just claimed segment.
Another thing to consider might be your investment amount. If its very little, the cluster might be extremely small as well.
There is a minimum purchase amount. Then it means Dev calculated the sum incorrectly, if 0 is obtained? Either an error in the contract, since any minimum if divided, still 18 decimal places are enough to not turn out 0. In short, the first impression never deceives. I immediately found this project strange. Well, that's right.
