Arena incubator cycle changed

Either im really lucky or something has changed… right before the patch i got a 24 hour inc i remember opening rigjt after an epic strike… then on wenesday i got another 24 hour incubator… i had one 12 over the weekend and im back to another 24 hour…

Now ive still burned through the required 8 hours to get to them but im still getting more 24 then 12.
