No, Bitcoin and its successors are made to handle this exact scenario from the beginning. It's common on every coin. There would be no cryptocoins left today if they weren't made to survive this. Don't call me mate. Why do you think coins like Bitcoin require you to wait an extremely long time for "confirmations"? Why is an arbitrary number of "confirmations" chosen as "probably good enough"? This is exactly why. Forks can happen constantly. These coins are eventually-consistent by design.
