If you play by rules that are not the rules that are in the book it is unsurprising that the results you received were not the results generated by the rules in the book.I didn't see this problem IME. Likely because we edited the magic items list. Not everything in the book existed in the world, and even if a particular thing did exist, we had to discover it in character.
Which would be a houserule. And honestly, a less effective one than the houserules you can easily access by clicking a link in the first post.Ignoring the optional crafting section, yes, they do have a range. The crafting section likely went high to semi-discourage crafting, but for a campaign with more magic the middle or lower values can easily be swapped in.
Putting all the flying stuff aside as it isn't the main point of the thread.
Except it kinda does because of what happens when the PCs go back to town and realize that the price that people will give them for that potion is completely ludicrous. And that they can use it to buy mercenaries or elephants or castles or other things which actually have a hell of a lot more utility to them as adventurers than the potion ever could have.The price of consumables is a little funky. A price adjustment (x.25 or something) should be all that's needed. Still only a problem with using the optional crafting rules or buying, which won't affect many games. The fact a potion of flying is unusually expensive doesn't matter when you find it in a dragon hoard.
