Changing bill drop off stockpile setting causes UI render exceptions

[SumNutz]

What went wrong?

• Changing the stockpile settings for bills (in my case, a make kibble bill on a butcher table) causes UI exceptions, making the ingredients and extra info panels on the sides of the bill dialog to disappear and continuosly spit out error in the debug console

Steps to reproduce:

1. Build butcher table
2. Create make kibble bill
3. Change deliver to setting from "Take to best stockpile" to any other stockpile
4. Exception occurs

Mods?

I'm gonna fire up two quick tests with only Math! and TDS bug fixes and then only Math! see if it still spits out errors

[SumNutz]

confirming that TDS bug fixes is not the issue, Math! itself is throwing errors on UI window rendering
