Perhaps these have been covered but my search got back nothing relevant

1. Black bug issue - yes just mentioning that I have it.
2. When ever computer goes LinkDead and I restart game I end up either falling or \"You fell off the end of the world and died\" so I end up in hell and have to make that trek, which puts me on the plaza which is of course pitch black for minutes.
3. Though I have killed 6 rats I have no EXP to show for it. I did already sell the pelts and eyes - but nothing appears to budge my EXP from 0%. What am I doing wrong?
4. I bought limited heal potions and used them, they did nothing for my HP. BTW my HP bar will show deductions but not replenishments unless I close the window and reopen it. Yes I knew that and yes I opened and closed that status window after I used the Potions (3 of them) and only had the 1 point of increase to HP. I Even queried help for how to use potions and followed their instructions to the letter.
5. Everytime I enter the sewards my HP drops to 87% right from the start, even though I do use the ladders. Is this right?
6. Just wondering, how can a rat hit my head?
