Minsc Bug

I have been expierencing a few bugs as of late, three in particular have been annoying, and the last I have not yet been able to solve.
1. Game freezes during or after Shou Long quest
2. Key to open Nai Kung Chi's tomb dissapears after I grab it
3. In Trademeet, Minsc repeats the line "Look, Boo. A Pretty Nymph" on an Infinite Loop

I found hardly any problem's before this.
My Current Party is:
1. Me
2. Minsc
3. Angelo
4. Neera
5. Viconia
6. Hexxat

Mods Being Used:
1. Angelo (Duh)
2. Auren
3. Wheels of Prophecy
4. NPC Strongholds

Currently in: Chapter 3, About to Leave Trademeet after finishing all the quests there.
