Evolution suggestion

Normally, if you decide to evolute a player it means you want to evolute them completely to make them stronger.

Why is evolution done in stages, and why do I have to manually intervene between each stage to advance to the next, even though it's mandatory and not optional after selecting a player for this evolution?

you must merge all levels in one challenge or make process to other levels automatically without any intervention from me unless this is intentionally designed to sabotage the evolution in case I forget to activate level progression, or if this is a backport for people to exploit in glitches.
