0002253: Elven caravan is empty, has no items to trade

Notes
(0008119) Langdon (reporter) 2010-06-10 22:54	Next year the elves returned with five warthogs, again all empty. What's weird is that the "allowed weight" on the trade screen is only about 70 dwarfpounds or so, despite not carrying any goods. (I "o"ffered some of my trade goods to see if that would make anything show up, and was limited by the allowed weight). I checked the trade depot again with "T" to see if there were any "invisible" trade goods that merely did not show up on the trade interface, but there were no goods other than the ones I had hauled myself to the depot (no wooden goods at all).

(0008121) Footkerchief (manager) 2010-06-10 23:04	You transferred this save from an older version, right? The problem is probably that your elven civ is still using warthogs as their trade animals, but the new trade capacity default prevents them from actually carrying anything. Try copying the 31.06 raws over your save raws and seeing whether that changes anything. (you may want to backup your save first)

(0008123) Langdon (reporter) 2010-06-11 02:21	The game was genned on 31.05, but I remember I overwrote the raws with the .06 version in both the main raw/objects and save/region1/raw/objects directories. To verify, I took a seasonal save from the start of spring and overwrote the raws in that directory with a fresh copy from the .06 zip. The elves arrived, again with seven warthogs and no trade goods. I guess this save is broken as far as elves are concerned. I'll start a new game on .06 later and update this page if this problem reappears.

Adding [COMMON_DOMESTIC][PACK_ANIMAL] back under the warthog entry in creature_large_tropical.txt allowed warthogs to carry items once again, and the elven caravan arrived with trade goods. I guess once an entity civ generates its usable pack animals, it will not change if the raws are changed mid-game. This should only be needed for 31.05 games transferred to 31.06 - I guess fresh 31.06 games should have these tags deleted to remove warthogs from the list of allowable pack animals as Toady intended.

(0008137) Footkerchief (manager) 2010-06-11 06:50	I guess once an entity civ generates its usable pack animals, it will not change if the raws are changed mid-game. That seems likely. Good work investigating that -- it might be handy for modders too. This should only be needed for 31.05 games transferred to 31.06 - I guess fresh 31.06 games should have these tags deleted to remove warthogs from the list of allowable pack animals as Toady intended. Hopefully, yeah. I'll post a note on 0000325 alerting people to this problem.

Two elven caravans in a row have arrived with lots of warthogs and no trade goods. Thankfully this bug was the first one I looked at when I did a search on "caravans" :) I'll use Langdon's workaround
