Just to add – I use Wifi as well. Would this be a factor? Thanks.
If it’s an actual crash and not a disconnect, very unlikely.
I’ve recently seen a number of people with crashing errors though that end up boiling down do a DX error, and is mitigated by reinstalling graphics drivers. I’ve reports both of crash-to-desktop crashes (no error dialogue) as well as with dialogue (which ends up weird, because the game will continue operating for a bit if you don’t acknowledge the error; of course, you can’t send inputs, but you can see the middle of a fight).
I was also hit by this issue, also doing crafting, using a homemade bot. I found that crafting in my empty apartment also mitigated the issue, since it wasn’t drawing nearly as many objects.
