+1 for increased market item reduction and optimization. There's already flooding but it doesn't seem to take into account some factors like color. Browsing the market lately can cause decent lag depending on the category. It might be a good idea to slightly increase general flood limits and take out some of the specificity that allows people to sell over intended thresholds for certain item types. If someone wants a specific color, quality, etc. they can always post for direct sale options.
I wonder if vNPC purchasing could scale slightly and automatically with: 1.) active player count and 2.) variety of items based on modifiers (colors, wood types etc.) to represent a slight increase in population with the MUD is more active and an uptick in purchasing because people are seeing there's more to choose from.
"You hear the Woses, the Wild Men of the Woods... Remnants of an older time they be, living few and secretly, wild and wary as beasts."
It is my understanding that browsing the market doesn't cause lag because it is done in a separate thread. You could `list dye`, and then walk into another room or start rummaging around in your bag and then the market list pops up. So it is slow, but it isn't lagging, it is deliberately delayed by running in a separate process but you can still look, talk, or otherwise interact with the mud.
Regarding wilderness janitoring: I'd like to suggest that bushcrafty or druidic types have an option outside whatever the new janitor limit is for some kind of safe wilderness caches. These would be containers only they can access via either a druidry spell or bushcrafting camouflage technique. These can be gm setup in specific locations so there's a limited number and would not be player instanced (gotta share), but would allow them to retain their wildernessy independence with a more permanent and qty-limited storage option. Everyone else can deal with the new hidden janitor like normal.
I believe bushels of wheat, the threshed and winnowed grain, and flour could all be considered for bundling. They're all functionally identical, and they don't have any "bites" or decay (at least not that I'm aware of).
