Erro Defense Missions Infestation

[oOVERDUGOo]

Hi I have many doubts about the missions infetacion first is priate play those missions bow dread that supesta mind has an ammo 72 down arrows automatic mind 30 arrows and when I run out of arrows I run out of ammo in LATRON gun is very frustrating to run out of ammo all the time this error happens to me with other weapons like the other one as a weapon that has hit 13,000 damage explocion hits 0 to some infected in some Estapar only hits 0 I have photo of errors but I would like to esplicaran me if it is normal for the game to walk so there really is something wrong or bad about the game.
