[2020] AA trap's healing perk do not work and more

I ran some test with my friend in CV endurance,found out that if you rolled x2 'heals attached building 4.8% of its max health every 10s',it will only heals 4.8% every 10s,which should be 4.8%x2.

Also,AA traps stop healing building in late waves,I think it can only heals for a certent amount of health ,I don't know this is intended or not.

At last,AA trap still target the bullets that come from HotMix,but if you fire HotMix from 3 or more tiles away,it won't.(I believe HotMix's range is 5 tiles,correct me if I'm wrong)

btw,my ENG is bad:/
