That is exactly correct.I'd have to wager that you were saying "I've added this thing that will detect donations from sources other than autosell, but first it will have to have all those other sources programmed into it; the hippy orchard profits are the only source programmed in, so far." Am I close? (insert friendly grin)
The hippy profits are listed in the message; Bale said it says "Oh, hey, boss! Welcome back! Hey man, we don't want to impose on your vow of poverty, so we donated 4248 meat from our profits to the human fund in your honor. Thanks for getting rid of those worms, man!"
The other quests with fixed payouts give unique messages - except for the Nemesis and Wizard of Ego, as I could tell from your report. We can distinguish via the URL you visit, though. Revision 9731.
Items that give meat don't seem to report the amount - which is a problem, except for those that have a fixed payout, like the Dolphin King map and the chest of the Bonerdagon. They all seem to have unique messages. I have the messages from the Wiki for the following items:
ancient vinyl coin purse
black pension check
old coin purse
old leather wallet
orcish meat locker
Penultimate Fantasy chest
Warm Subject gift certificate
but until/unless they start including the Meat amount in the message somewhere, I can't parse them. That is worthy of a bug report to KoL, I think.
The only other donation I don't have a message for (I've not seen it and it's not on the Wiki) is the 3,000 Meat from getting the pirate fledges. If you notice that one, post it here, please.
Thanks.
