1. The "switch execution to trigger" trigger action can execute triggers that are disabled or don't have any remaining calls.
2. When a trigger with 0 calls is switched to, that trigger will gain infinite uses (probs cuz its remaining calls gets subtracted and becomes -1)
3. If parameter 'A' doesn't point to any existing trigger on the map, the trigger action will default to executing the first trigger on the map (which causes some very hard to track down bugs). It would be better if it threw an error instead.
