[Bug 1.126] - Game crash when multiplying an exponent with a negative number

[man_with_flan]

While modding the game I’ve noticed that the game will crash if you multiply x^decimal constant by a negative number such as -0.5. This happens both when the multiplication is being done in a mod or in the actual game CSVs. If the object that has this multiplication exists at the start of the game the game will crash while loading. If the object is created later on the GUI gets messed up missing the policy group border lines and having a white background.

This crashes the game:
-0.1+(-0.5*x^0.5)

Although using a minus instead works totally fine:
-0.1-(0.5*x^0.5)

[kram1032]

does it work to delimit the multiplier? Like this:

-0.1+((-0.5)*x^0.5)

This issue seems to be part of a much bigger problem that I’ve outlined here:

[Bug 1.126] - Parsing of Exponents doesn't respect parentheses

The way that the game parses exponents is incorrect. They incorrectly include the previous term of the equation even through parentheses. Equations like: 0+(0.5x^2) are processed as if they were: 0+(0.5x)^2 Same with addition: 0+(0.5+x^2) is processed as if it was: 0+(0.5+x)^2 Parentheses: 0+(0.5+(x^2)) is processed as if it was: 0+(0.5+x)^2 Take this example policy: #,Test_1,default,0,0,0,0,FOREIGNPOLICY,20,200,0+(1.0x),0,0,500,0+(1.0x…
