I am seeing some unexpected behavior in the new parametrization feature where any parameter formula that would result in a negative value is always evaluated to INT_MAX (2147483647)

for reproduction I've created a simple blueprint that demonstrates the bug. the value is just the negated stack size but this also fails with constant expressions:

Code: Select all

I swear I didn't plan the end of the string to read as "Bug"

Can confirm, ran into this when trying to paramatarize a dropoff train station.

Same issue. I checked to see if it was documented to only work on positive numbers but I didn't see that anywhere. I can work around it by just negating the formula result in a combinator, but it feels strange to need to do this.

Hello, this seems like the same issue as this: 116342
I fixed it for 2.0.12
