I've been trying to find some info on default potion gold values. Specifically, did gamesas change the formula for calculating them in a patch or were the values listed in Oblivion.esm created with an older formula which was changed prior to release of the game.
The formula for determining potion value is: Price = (Effective_Alchemy + MortarPestle_Strength*25) * 0.45
Prices are rounded down, so if you calculate a value of 21.8, the value will be 21. However, the price is set the first time you make a specific potion; all subsequent potions with the same name, same alchemy effects, and same strength will have the same price.
Secondly and more for personal curiosity. When movable objects (items, creatures, npcs, corpses, etc) glitch and drop through the world mesh into the void, does any one know what happens to them? eg, Does the game auto-disable them or is there a 'bottom' somewhere down below.
This is a hard one to answer. Some cells definitely have a "bottom", while others seem not to. I've used the "Toggle Collisions" console command to get "outside" walls and I sometimes hit a "bottom" when I turn collisions back on. Even when I do hit "bottom", the falling animation still plays, so the only way to really tell is if something static is still visible and no longer seems to be moving away from you. If there's nothing visible, it looks like you fall forever (although I usually end up magically back within the walls if I fall for too long).
Edit: If there is water in the cell, you will fall until you hit it. I've never tried to see if there was a "bottom" to the water inside cells.
