I get why you’re annoyed, but with 3* Lv65 Era characters, who were you ahead of that is now ahead of you?
The update bug made it impossible for people who had taken units to 4* or beyond to Level their era units to the highest possible level. CG’s fix has basically made it trivial for all players to take their era units to the max available level for the final 5 days of the Era.
If you’d worked hard and earned better Era currency rewards through a decent daily leaderboard position (which I’m very skeptical of for 3* Lv65 era units), you’ve enjoyed the fruits of that for 79 / 84 days of the Era.
The people who should rightly be annoyed here are people who used crystals and/or real money to buy era materials that were subsequently handed to them in vast quantities for free. I don’t accept that you are in this category.
