I've been catching up on Chicago Fire and i've got up to episode 4 (Infection Pt 1) and all 4 episodes have so far skipped bits. At first I thought it was just an issue with that episode (at the time, episode 1) then it happened again on episode 2, 3 and now 4. I can't remember at what time for the first 3 episodes but for episode 4 it happened at 25:39.
No idea if the rest of Season 8 from episode 4 onwards is like it but if the first 4 are, i'm going to assume they are too
That episode was part of the cross overs they do with Chicago PD & Chicago Med.
You need to watch in sequence to see it all, looking at the episode guides for the other shows will let you know which order to watch them. They’ve done it in a few seasons.
