Okay, I've run into what I consider a real nasty issue. While I'm playing the game, when my current bank of BC reaches between 19,500 and 20,250, my economy begins to fluctuate every turn. And not a little either. Looking at the economy graph, the spikes are noticeable even on the little display on the main screen. The best example: during a 'boosted economy' even, I was making almost 13000 bc per turn in taxes. I was spending around 10000 bc so my net was three thousand. When my bc total hit 19873, my tax income plummeted for one turn going to less than 9000. The turn after that it jumped back up to 13000 again. It went back and forth until I crested 21000 bc in the bank. Now, here my main problem. When it settled down again, it settled at the new LOWER tax number, even though I had been making 13k for almost a year and a half (long event) and that my bank had been upwards of 300k before I decided to quick by upgrade a bunch of dreadnaughts for 290k.
Basically because of this bug or whatever it is, I lost over 4k worth of taxes permenantly. Since this happened, I've recreated the effect over 20 times so I know it wasn't a random thing but something that happens regularly. I also noted that it also happens to the computer players as well, though they're usually too broke for it to happen

I know markets fluctuate but this is ridiculous. And it if does eventually even out, I would think it would even out at pre-fluctuation leves, don't you? So, I guess this is my long-winded way of asking "What the hell?"
I'm currently usinn V 1.31 and looked into 1.4 but saw no mention of this so I wanted to get input on this. I've never had this happen before I upgraded to 1.31.
Thanks be to you who shall shower this ignorant peasant with the glory of your wisdom... (IOW, pretty please tell me what's going on!)
