Greetings from Com2uS!
We would like to address an issue that was found after the v4.2.8 update.
- An issue where it shows as if the monsters, excluding the one you tapped to level up the monster, didn't have their level ups when you are using the EXP building booster in the EXP building, where more than 1 monster is placed.
Please note that the level up and EXP acquisition are being processed properly and it is only a display error.
If you're experiencing this issue, we kindly advise you to reconnect to the game or remove the placed monsters from the building to see the content correctly.
We're currently preparing to release the v4.2.9 update to resolve this issue as soon as possible.
We sincerely apologize for the inconvenience and we will do our best to prevent this kind of issues from occurring again.
Thank you for your understanding.
