yep. a couple reports here on forums too, and my clusters discord.

Looks like plarium screwed the pooch pretty hard, *again*

are they going to let scores stand and mess everyone or they going to fix

my money s on they will give some bs reason why  they cant fix

my question is why did this happen? i mean its simple clash ending at what time, then make changes start 1 hr beofre 

They did that.  The maintenance was timed correctly, but apparently, there was never anyhting to prevent opening/starting a Hydra run before the next Clash started, and nothing was coded to force a close/update for all games after the maintenance.    

but how did they miss that?

1. tl;dr some people managed to get around things by starting runs before maint
2. plarium has been made aware
3. don't know what if anything will come of this (outside of people ending up with ginormous scores relative for this week)
