Same issues here, and there has definitely been an update to the game, the main login page is different and I was directed to a tutorial as well when initially loading the game. In addition to only receiving wheat from crates, when I "harvested" several items (cow, chicken, goat, wheat carrots, soybeans, sugarcane), I only received 3 items per harvest despite most items being upgraded to 2-star and previously receiving 6 to 8 items at harvest. Also, I was given a wheat "upgrade card", but the image is all white instead of the color my other upgrade cards are, and I am unable to merge the card with 2 others to get a further 3-star upgrade. I'm at level 18, and my progress has "stopped" since the update launched, any wheat merges I made didn't change my progress total toward level 19.
I'm using a Dell Inspiron laptop with Windows 11 version 25H2, Google Chrome Version 147.0.7727.102 (Official Build) (64-bit), and I didn't change browsers either as this is clearly another "game glitch". I don't understand why changes/updates to games are made when everything is working fine and no changes are needed. Instead of making unnecessary "updates", please spend some time "fixing" actual existing problems that have been reported and not yet resolved.
