Everytime I see a 4.0 Nexus thread It usually always seems to be about the food plugin, now I don't think anyone truly has the right to complain until they try it, because when you do you'll realize that you rarely come in contact with the expiration date. The time I've played I've found out something about the food plugin.
1. Any argument about bread is foolish, it just is. At the moment it has a 3 day long expiration date that's wicked long, it may not sound long but it's wicked long. And what is bread made out of? Wheat! And wheat has no expiration date, so what do you do? You put it into a hay bale and make bread when there is demand, which brings us to supply and demand. Only make what you can sell or eat never more than that, or else you risk the spoilage.
Hopefully that makes sense and explains some of the problems that you may have with the plugin.
But in 4.0 we'll all be able to play with the great plug-in and hopefully any troubles you have with the plugin will be resolved by then, but until then enjoy Rp'ing!
