I've noticed that whenever I enter the game, the daily gift interface tends to glitch out in visual and audio terms. This time when I loaded just the black gift background was visible, while gift itself was not. Sometimes even the audio bugs and sounds like it's repeating itself and the like.

I have an issue regarding the sculptures and my "main" world. I made it before the guaranteed 3 sculptures patch and its missing a bishop. I tried tumbleweeds but it didn't drop, though the rooks and knights did in both variants. Is there anything that can be done? Maybe other ways of obtaining chess pieces?

I know that the new update from now on guarantees a 3 suspicious sculptures set, which is great, but what about the world that existed before the patch? I have tried getting the chess pieces from tumbleweeds but only got pieces that existed in my world; knight and rook. I've got every variant of those two, black and white (even a green gem!), yet no bishop. Not once. My base is littered with these chess pieces and I believe we should have another way of acquiring them. Maybe a 10% drop chance after giving another piece to the pig king? I can't just leave and make a new world, because I've been playing it for almost 800 days and I've done so much.
