Cant access my community list, only on liftoff (meaning no problems on web or other apps). I remember playing around check boxes in the list, and subing/unsubing communities when this nil error occurred. Sorry there are no more info, it crashed few days ago, can't remember all the details
Doesn't work for me as well, but I'm seeing something else.
I see it constantly when trying to browse communities, but it happens a lot in other occasions like opening a post to see comments, accessing a certain community, etc.. 
thats another problem but it happened to me too, reload should fix the problem. it looks like a fetch problem while mine should be due to not handling null value. Here, there is another post about it : https://lemmy.world/post/990536
Thank you I thought it's related, didn't try to hijack your post lol
nvm :) have a good one
Just for lemmy.world? I noticed it just stopped working on liftoff but beehaw is working.
lemmy.ml also does not work. don't have beehaw
Its not the app. It's just lemmy.world.
Above works for me
community list for me literaly works everywhere but on liftoff, thats why I suspect liftoff
