Fix Float Multiplier Errors

[earth2travis]

In the launch flow a float in the multiplication results in a console error that prevents the transaction

[skuhlmann]

potential fix:

this field would change to a drop down and the loot per value would update based on the min yeet input.

so you put in 1 on min yeet - loot per is a drop down with: 1 10 100 1000

you put in 6.66 on min yeet - loot per is a drop down with: 6.66 66.6 666

temp fix: locked the multiplier
