I know it's not a major bug. So I've noticed that the Best Hit seems to cap out or my current game is glitched. I'll give you an example:
Tower: Blofeld
Lvl: 99
Best Hit: 1.8 B
Dmg Dealt: 6757.8 B
Creeps Crushed: 8.419
Base Dmg: 66.176 - 99.265
Dog Add: +2675.6%
Crit Dmg: +4756.6%
Crit Chance: +739.3%
Multicrit: +6
Avg Dmg: 2.4 B
Base Cool down: s2
Atk Speed Add: +1394.3×
Cool down: 0.1s
Item Chance/quality: +3214%
Gold Chance: 0%
Luck: 10%
Exp: 10%
I've been watching my crit hits and have seen as high as 6.452 B. Even the Avg. Dmg is over the 1.8 B that is being tracked. So I know the Best Hit should be at least 6.5 B and not the 1.8 B that shows.
This seems to have happened around wave 500ish. Now I'm not able to confirm if it happens to any other towers as well.
If I could figure out how to upload a pic of the tower from my phone, you'd see the stats shown above.
Keep up the great work mastermind.
