hmmm. seems like randint(0,1) may act different on your mac. on windows with python 3.7, I get numbers numbers 0 and 1.

and python 3.4

[jmerc77]

please verify the error for latest update. many fixes have been made.

[jmerc77]

ran in to this a couple times on windows too in the past. but may be fixed now. added a if based catch to try to fix the issue. i believe the problem was to do with only having 1 possible value to choose from. the if fixes this.

[jmerc77]

It seems to be fixed now. did lots of runs during updates and this error has not come up anymore. fixed other issues with the general design too.
