An SKSE plugin that fixes some problems associated with player-enchanted weapons after game reload. Namely, the fact that their gold value increases significantly and they begin to consume much more charges per hit (problems which become worse as your Enchanting level gets higher).
Also of possible interest to modders -- this plugin restores conditions to player-enchanted weapons. While working on the plugin I noticed that a bug has previously prevented player enchantments from inheriting any conditions from their base enchantments, they instead come out condition-less after they're made.
