Expected behaviour

I should be able to mark shows as watched and unwatched without interruption. When I mark a show as watched it should add to my watched hours, when I mark a show as unwatched it should be removed from my watched shows.

Actual behaviour

Occasionally when marking a shows as watched or unwatched the application will crash.

How to reproduce

1. From either a fresh install or existing install select enter the application and select a TV show. For the purpose of clarity, select "Supernatural"

2. Select the episodes tab.

3. Quickly switch between marking the two different seasons as watched and unwatched. For example, click season 1 watched then season 2 watched then season 1 unwatched and then season 2 unwatched.

4. Repeat step until a crash occurs, the time this takes to reproduce varies. The method mentioned seems to reproduce the issue everytime across the devices mentioned a reproducible below.

Please note that the above steps were not the first way I replicated this issue, this issue first occurred during normal application use, but the above is the only way I can seem to replicate over and over again. Please note I checked the error on the standard behaviour crash and the crash mentioned in my steps and it’s the same exception. I realise that the steps provided may be a low priority crash so I would like to make you’re aware it does occur in normal use. The behaviour I carried out first was simply adding shows I've watched to my watched list and randomly it would crash, this will cause it to crash eventually although nothing I can state with replicable steps. I believe fixing the error mentioned below caused by the steps mention within the steps to reproduce will resolve the issue in standard behaviour too.
