I found 3 Bugs on 6.46 release.
1. When making tiny lumber mill lvl 4 x4 to tiny lumber mill lvl 5, it will make lumber mill lvl 5 (instead of tiny lumber mill lvl 5)
2. When player leaves, display wrong player leave and kill wrong player's hero.
3. In W3's singleplayer mode, -save feature is enable.
here's the replay link (number 1 and 2 occur)
