There seem to be several Mythos Cards that have different enviromental effects, such as weather, mystic, urban etc. Do you replace the environment effect when a new one is drawn regardless of which type it is, or does it only replace one of the same kind.
Example, Environment Weather. If you draw for example an Enviroment Mystic, would this be in play at the same time as the weather one, or replace it.
That being the case if the environment has a task that has to be done, and it is replaced, have you escpaed the task, or do you suffer the failed element of the card
The same question to rumour tasks, if the card is replaced (via drawing another rumour card) do you suffer the failed consequences.
