It happend when advance heroes. I tried on the same team with no upgrade and upgraded. The mod didn't work after some upgrade but work again sometimes if u continue upgrade that team or switch heroes (it's random on heroes, sometimes it work on all team, sometimes it work only for 1-2 heroes)
Updated the mod
- Added Damage & defense multiplier v2 ( do not use together with v1 )
Actual effect is applied but numbers is shown on the screen not reflecting it. ( you can try with 1 dummy hero and challenge boss).
