health loss when using the undo button #supper_angry ;-;

So,im really pissed about the fact that after all thoose undo button disables it still doesnt work properly,for instance me and my friend were duo qing and he went back to buy something,he was low hp too,he clicks the undo button bc he messed something up and all of a sudden a jinx rocket smashes him in the face,BOOM he dies and wham jinx kills me aswell,im not sure would have he survived even if he didnt loose hp but still this is an issue that wouldnt be bad to fix P.S sry if i had any grammar mistakes,its pretty late and i dont have time to check that ,hope someone hears me out
