Mangos Issues

Hi.. Just started a mangos server and playing for 2 days.. found some issues.. wonder if anyone could help or is facing the same issues?

1) night elf warrior, charge skill, sometimes will charge in and fall into the ground, causing stuck and die. After which not able to revive and have to go to spirit healer.

2) some loot quests not able to loot anything? e.g. timberling, big bone quest in auberdin (fyi, i had auto loot on.. not sure if this info is any useful)

3) some creatures in huts are underground.. killing them render them un-lootable for some..

4) cant revive my hunter pet if my pet dies?! it says i dont have a pet.... :(

anyone encounter such issues too?
