changing loot wats going on???

i do like 18-24 bk ls a day and leave all loots in mail until the end of the day and collect them (as i add all loot info to a tracker program)..however yesterdday like most days i like to have a running check on my egg haul...

now i had check my loot about 3 -4 hrs earlier and had like 90 eggs in 5 of my loots and a few 0 eggs drops...but when i checked again there were no 90 egg drops and no 0 egg drops every loot had 45 eggs instead ??...

i refreshed and low and behold all the 90 egg drops appeared and so did the 0 egg drop loots i am not sure whats going on that the game can show different loot to what was there before...?

if i refresh and refresh do i wait until all loots show 90 to get max eggs?...or collect each loot as it happens to ensure i dont get robbed by a loot changing bug ??
