change_variable and set_variable don't work

[Cheexsta]

At least, not as decisions...

Made a couple of simple decisions with the following code:

country_decisions = {
	set_variable = {
		allow = {
			ai = no
		}
		effect = {
			change_variable = { which = variable_test value = 1 }
		}
	}
	change_variable = {
		allow = {
			ai = no
			check_variable = { which = variable_test value = 1 }
		}
		
		effect = {
			change_variable = { which = variable_test value = -1 }
		}
	}
}

In-game, the trigger check_variable displays properly. However, the effect change_variable does not, and clicking the button has no effect. The code seems to work fine in EU3 (some mods use it but I haven't checked it myself).

The actual change is not supposed to show in the tool tip (or at least they are not shown in EU3 either). I use them extensively in MN and they work just fine, with the little kink (also in EU3 by the way) that when you do something like:

check_variable = { which = variable_test value = 1 }

It will only return true if the value is actually more than 1 but not when it is exactly 1.

I usually fix this by having a setup script with set_variable 0.01 but you could probably just use 0.99 in all the checks instead.
