The Jungle temple moved and most of it dissapeared. It was my main base since it was close to my starting location. everything I had stored in the temple is gone. Not a major dilemma in my life but it is pretty annoying to come back to from exploring an abandoned mine. and some large oak trees appeared on the area I had cleared. Even the basement has been replaced with normal terrain, wtf?

PS after trying to dig where the temple was to see if my chests and tunnels still exist I found that the dirt blocks regenerate after about 2 seconds and I can't dig in that spot.
