I discovered this bug prior to the recent update and expected it to be fixed soon; however, it's been over two weeks, and the issue persists. When you get Greevil Egg Relic, upgrade a unit, it will continue to grow up until you hatch the egg, contrary to the previous design where the egg would only continue to grow if the relic remained active.

This means that someone who acquires this relic will always have a 100% chance to reach the highest level, causing an imbalance in the game. I hope the team will address this issue promptly.
