I have been having the crash to desktop on Xbox one, i play single player and notice it more on The Center, not tried Ragnarok yet.
At first i thought it was maybe because my Xbox was overheating but after checking the forums i am thankful that i was wrong and i am not the only one experiencing this problem.
Seems to have started the past few weeks, and reading other posts on this thread i get the feeling it is some sort of memory leak. When mine is about to crash i notice that textures wont load in properly so i do the "admincheat saveworld" every 10 minutes. Happens more when i am at or near my base but i suspect it is because i have a lot of things there.
Really hope Wildcard can sort this problem out as it is becoming a tranq dart pain the ass for a lot of players.
Keep the peace folks and try not to rage too much
I was on Twitch when it crashed earlier, if you skip to 18:00 minutes on this video you can see the texture loading problems, where the video ends is when it crashed to desktop, hope it helps.
