Ah, forgot to mention there was no crash on the client side. This was not caused by a crash on the client either so no crash report was generated. It was just the banner block not dropping itself after being placed down and left for a few hours before trying to pick it up again.
It is as Jess described it. The banner does not drop itself unless it has just been placed for a few minutes.
Unsure if this helps but I have identical problems as this issue. Making a character on a different platform such as Android then reopening the same one on Windows 10 does not load at all and vice versa. I don't know how to force it to load since the Edit button becomes greyed out instead, only the delete character button is available.
