Nikita recently fixed this in a project. Here is the original bug report:
- I added an Affiliate Plan via Affiliates -> Affiliate Plan (ID: 1)
On the Brackets tab, I setup the following:
1 100 10 100 500 20 500 infinity 30
- I saved the Affiliate plan.
- I edited the Affiliate plan, opened the Brackets tab and saw that all of the Percents reset to 9.99.
Nikita can explain more exactly what was fixed, but as far as I understood, it had to do with how MySQL now stores DECIMAL(3,2) fields. This was also fixed in a couple other tables with the same problem.
Original bug report was for version 5.1.0. Also tested on 5.1.2-beta2.
