[LE] Story Manager Probabilities

[ZenoImperator]

The random encounters in Skyrim are dictated by the Story Manager, which uses nodes "WE Events" and "WE Road Events". I am trying to modify these nodes and the individual quests in a way where some events spawn more frequently than others *without* affecting the actual spawning.

For example, I tried to make additional nodes with the GetRandomPercent condition, which then had different quests in each node so that one node produced events more often than others. However, this only made quests spawn according to those percentages. So for the high-probability events, which had a 50% chance of occurring over the others, this actually made them spawn only half the time. I do not want this to be the case; instead, I want to ensure that quests spawn normally, but are grouped according to likelihood of occurrence when they actually spawn.

What's the best way to change the chances of certain quests of occurring over others?
