If we can reproduce it here, we can fix it. But as I said, even though it looks very strange, compared to things like online desyncs or moves being wrong or dropping inputs or game crashes, this bug is considered unimportant because it doesn't DO anything besides look weird.
Yeah, we know. It's around 1 in 250,000 chance to happen, and we were never able to make it happen for us so we couldn't fix it. We made some guesses and tried to fix it, but they didn't work.
However, unfortunately, to devs this is a MINOR bug, compared to the game crashing or whatever else.
