Hello CC,
The max trade cap from 1G should be rescinded. I post it under bugs because the max trade cap is 1G but with the mythical items the 1G max can be exceeded.
I will give you some example on the screenshots.
For the magic seed in mystic it have a basic price of 138,750,000 and i guess the mystic items are 25x basic price set from you.
But let us take the TH price cap at 10x i should be offer it for 1,38G.
So the actual max from 1G get exceed.
