Thank you for the question, Julie! The particular policy in question was instated after a mod-run plot event in October was abused in a high amount by players for use during activity checks for several months after the event had occurred. As we have indicated, this therefore made many of the cast at that time invisible from more recent game events and for long periods of time thereafter, and so the policy was enacted to promote increased participation and visibility to all characters.
However, as this would be, as indicated above, the appropriate venue by which to make a request that we officially change this policy, we are of course amendable to meeting player needs as it suits them at this current time. If players would find it more accommodating to use the last month's game events to meet their activity check, we are very receptive to such requests and facilitating continued player logging activity and ease, while also not bogging them down with past-dated logs. If you have any further questions or requests regarding this particular topic, please feel welcome to indicate them here!
