The API seems to show that your actual target multiplier was 1.14:
~snip~
It's really weird that the frontend displays 1.13, but it's likely just a rendering bug. It doesn't make a whole lot of sense for Stake to try to cheat over $2 bets. Do you happen to remember what multiplier you were going for at the time?
I am guessing there could be some rounding out error? ~
~ I checked mine all and they seem fine, but here we are with a proof of one guy not getting fair results, so they should make the announcement and defense against this.
How the games actually works there! I have also observed some unusual result while I'm setting the target multiplier from 1.13× to 1.16×. To make it clear, when I'm setting the target multiplier at 1.13
The bet details shows
- Multiplier: 1.13×
- Target :1.12×
The multiplier and target shows correctly in their bet view model if my target multiplier is out of 1.13× to 1.16× range. But their system shows 0.01× less target when I'm inputting the ‘target multiplier’ in that range.

I have also made a video while I was checking this out. If you haven't understood my above statement then see this video to realize it properly:
