Today's update while big in its own terms for balance, also included the ability to skip all boss cutscenes, This is very impactful on run times and we should see a lowering of all current times for essentially free.
we know it isn't ideal to have times be constantly changing due to game updates but beyond wiping the entire board when changes like these happen there's not a whole lot on our end we can do with keeping the boards consistent and fair for old/new runs. We talked with the devs before the patch hit about a "Add remaining skipped cut scene time to in-game time" which would allow the convenience of skipping with no IGT change but it was shot down as it didn't make sense for anyone else but runners so it's likely to operate like this for the future. If any solution that isn't - Calculating exactly how much cut scene time was skipped and adding it ontop of in-game time for the boards, then we'd love to hear it. (Reason we wouldn't do this is it'd be inaccurate and a ton of work for the mods). As of now runs will just go ahead as normal with the free time-save :)
