Skill, weapon set

bugs I have encountered regarding skill interactions, weapon mechanics, and Cast On Critical (CoC) functionality. These issues are significantly affecting gameplay. Here are the details:

1. Skill & Support Gem Interaction Bug Sometimes, after reallocating passive points or removing/re-socketing support gems, the main skill becomes unusable in its original setup. It seems to get "locked" and fails to function even when returned to the previous working configuration.

2. Staff and Rune Bug

Weapon Lock: I am unable to use any Staff other than the one currently equipped.

Rune Issue: Socketing a "Level of All Spell Skills +1" Rune into a Staff renders that Staff completely unusable.

3. Cast On Critical Strike (CoC) Issues

General Failure: CoC frequently stops working for no apparent reason. The only known workarounds are to craft a brand new item or to trade the bugged item to a friend and trade it back to reset it.

Weapon Slot 1: CoC specifically fails to trigger when used in Weapon Set 1.

4. Blink and Cooldown Charge Bug There is a bug involving "Blink" and the "Ancient Reserve" (or related cooldown mechanic). Even though I have stats that grant "+1 Cooldown Use" (which should allow 2 uses), using Blink seems to block this, limiting the skill to only 1 use.

These bugs are occurring frequently. I hope you can investigate and fix them soon.
