Yes, as of 1/22/23, still bugged. Over two years later....
I get it. You are a small team now, not a lot of resources available to fix bugs and, for whatever reason, you're obsessing on a 64bit version of the engine. But, if you aren't going to fix the bugs in old content. Then make that old content skippable for new player and characters. Don't make them slog through buggy content that isn't going to be fixed to play the new content.
