Game glitched and allowed me to use 2x infinite incubators

I was walking outside my house this morning while playing. I tried to put a new egg in my infinite use incubator and I the app sorta glitched out right as my phone dropped off our home Wi-Fi. In the moment it was actually pretty frustrating. I come to work and find that I actually lucked out and got 2 eggs in my infinite use incubator. I might try to see if I can recreate this scenario later in the week
