I have been using random numbers in the scripts function to trigger certain outcomes in the level that I'm creating.

I create a number with an initial value of 0, then in the script I trigger a random number event which gives the number a value between a series of integer values, say 1, 2 and 3. When actually running the game certain numbers never come out, so 1 and 2 would come out, but never 3. Conversely I have another number event where 3, 4, 5 or 6 should be chosen, in this event 4, 5 and 6 appear, but never 3.

I find this quite bizarre. Has anyone else experienced this? Does anyone have any advice? I can provide more details on the exact events used it needed.
