When the new round started, all the money I had in my bank account vanished. I had at least 82mil and now it's gone.

All the money and points were converted to new-round values. I think it was $100 in the old version = $1 now, and 24 points prior to round 4 are equivalent to 1 point now.

Exactly. The reason I did it was a good one, but it is too complicated to explain again

You have not actually lost money, since things will DEFINATELY be cheaper. If there is anything that is too pricey, it will be knocked down to keep it the way I wanted it to be.
