I was betting on 85% win chance, after pressing roll dice several times I decided to change from <85 to >15 (14.99). The thing was that I pressed roll dice and instantly after I changed the roll over to win 14.99 before the roll happened. This lead to this; which is kind of weird:
As you can see, instead of changing it to >14.99 it changed it to <14.99 which is the complete opposite in win chance and everything.
You can all try it out, it does the bug many times, as soon as you press roll dice, press the button to switch from roll under to over and your next bet will bug.
