I wonder if the change to the candy corn gobbler is bugged, or else has some internal limiter involved? I just bought 83 from it (~250 candy corn pieces) and got 1 hour of EXP buff, 1.5 hours of magic find buff, and about an hour of the others. PReviously, I would get 5-6 hours of XP buff alone using about 750 candy corn pieces. A guildie of mine reported buying 1k worth of candy corn pieces form it and got 1 hour EXP buff and 2 hours magic find buff. I know it's meant to be random, but that seems disproportionately weighted toward not getting the buffs I think.
Side note: I posted this elsewhere in a totally unrelate post accidentally, so I'm trying agin in the bugs forum witgh a fresh one to see if others are noticing the same thing.
2nd edit: I can further clarify this by saying that I left the # to purchase at 1 and just clicked buy over and over about 15 times (spending 45 candy corn pieces), and I got 1 hour of the XP buff and 30 min of the magic find buff, plus some of the others. So are we meant to still be buying this one at a time from the new vendor interface? I mean that beats waitin 5 seconds between purchases, but that could be better explained if that's the intended functionality.
