Yeah,
I had an amulet early in the game that gave +1 elven sight, plus I had 1 skill point assigned to the skill as well. On reloading a save game, I could tell from the minimap that removing the amulet reduced my visibility, so effectively a +2 bonus was being applied, just not displayed correctly (only showing +1), unless the amulet was re-equipped.
I assume its the same for all other skills with +skill items, but I don't remember testing them. If it makes you feel better, I suppose one could always re-equip the items after loading, but that would be a little sucky, wouldn't it?
The way the game calculates the total points in a skill is a little strange. It seems to store the skill points assigned by the player and skill points from items as a single value, instead of keeping them separate, ie "base" skill points assigned to a skill within the skills window, and those given by items, and then displaying the sum of the two to the user.
I say this since lvl requirments are associated with skill levels, it should use the "base" skill points assigned by the player as the actual skill level, instead of the player having to unequip items that give +skill so you meet the level requirement, assigned a point in that skill, then re-equip the items.
If that sounds a little strange, don't worry about it. I'm not. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
