Huh? (in General)

I just had 136 BA, and after fighting someone, the next fight said that I had used up all my BA, and now I have -1 BA. This is strange.

-1 usually means infinite in coding parlance. I think this is a gift horse/mouth complex. Run with it and dominate. :D

I had the same thing happen.
I made a post here and nothing was fixed, that BA was lost forever.
I'm a supporter too, shame I wasn't supported in return.

-1 BA is quite easy to attain...try visiting the store with 0 BA

The point is just what Ax3 said in his post: that I had more than enough BA before and suddenly I have -1.

Yes, I have experienced this as well, had 48 BA, clicked Heal, then I had 6 BA.. so I use the 6 BA, then at Home with 0 BA, click Home, suddenly 48 BA again and lost the XP from the 6 fights.
No complaint in the end but very wacky. Happened yesterday.

are you guys that you just didnt have stale cookies.... try clearing your cache, and cookies

also don't use backspace too often.

Looking at the fightlog for flamewind would suggest he went from ~100+ BA to zero.

For sure he didn't use all 160 over the period when he posted so unless at time of post he didn't actually have -1 BA left then I would agree he had a problem.

That said, it doesn't happen often, however it's not unknown for a little server hiccup like this to occur and you can as often gain a few extra BA as lose them. I think you have to put this down as "one of those things" and let it be.
