Okay, so I loaded Blockland, went straight to Construct, went to test out the new vehicle events, and found:
All of my downloaded events (Water Bricks, Variable Events, Vehicle Events...) were gone.
Then, I loaded my Landscape build, and Blockland crashed. The only reason I could think of as to why this would happen is that I loaded it at a friend's server and it glitched up.
This is probably the second-worst problem that has ever happened to me, please help!
