I’m really not a big enough nerd to clearly answer this question lol.
Basically the xbox uses a cache to store data so it can be loaded quickly. Over time or after something like an update, a disconnect or in the case of some games (looking at you GTA v) a lobby change it can become full, or have conflicting data. When you use instant on the xbox doesn’t clear the cache when its in stand by mode or if you choose reset.
This is why when you put in a support ticket for almost any issue on xbox the first step is a hard reset.
You can avoid many issues with the xbox by
- Avoiding the always on power option and using energy saver instead.
Or
- Shutting down the xbox by holding the power button until it turns off - every time.
This isn’t really an issue with d2r, but a flaw with the xbox and with computers in general.
Hope that makes sense. Cheers
