we are human,it could just be a mistake and u just hadnt noticed.to check this all u have to do is test it.this one was like this ? capture a couple more and this time be sure to check the buffs,enhancers...
however
if the boost factor was applied correctly,and the buffs are there honestly
if there are no champions involved as well,
this can NOT be explained, there is no other factor that can affect an action by that extent,it is just a glitch.
and if that is a glitch,still there is nothing to worry about,these thing happen very rarely only in server update times and shouldnt make u more troubles in future,still if it does make a topic in Bug reports
