I'm not sure what's going on but the game appears to be very buggy to me.

I'm using Windows XP and play on Firefox browser.
I do play around with hidden files and folders in my system but am very careful when touching them.

Two days ago, all my characters have been wiped clean. Probably it's my fault, I'm not sure.

Yesterday I start a new character (again) and I notice an old bug:
When I killed a mob, its hp bar still appear and goes beyond negative value.
My life/mana bar keeps blinking although I'm out of combat & regenerate as if I'm at rest.
Continuing casting damage-spells at the dead mob will level up my skills.
On one instance I ^killed^ a dead mob in a single hit; gaining xp, gold and a rare (yellow) item

Sometimes my hotkeys doesn't work.
Camp require multiple clicks to save and exit. And if I'm unlucky, all my characters will be gone if I camp/exit the browser.
Sometimes the character creation panel doesn't appear to me. And if it does, there's a chance for the 'Create' button fail to work properly, causing further glitch and characters wiped.

I have tried uninstall Firefox, clearing all the associated files before reinstalling, and restarted my computer many times.
Things I have not try: 1) Play on a different browser 2) Play on my brother's pc.

For the past two days, nobody mention of a similar occurrence in this forum nor in Kongregate.
Sigh... I hope I'm not alone on this problem.
I'll probably reformat my system again next week, hopefully things will turn to normal again.

Hum, some of these problems could possibly be caused by the page scaling trick I was using to adapt the screen to the window size. I removed that since I noticed it was causing some weird graphical problems like aiming at the wrong things. As for the local storage problems, that is troubling, but I'm not sure what could cause that. Local privacy/cookie policies can definitely cause problems of this sort. I've had the same 14 test characters, one of each class, on Firefox for probably more than a year now? My rogue has more than 9 days played!

In any case accounts are coming soon and that can help alleviate that problem.

The rest, I'm really not too sure yet.

All these issues seems to have disappear now; things are back to normal.
Woot!

Must have been something odd... these things happen with browsers.
