I completed Node 4 of Lap 4 of the Heroic Race and signed out of the game. When I went back to the game later Node 4 had not saved and I only got credit for feeding two dragons. I play on PC. Clearing the cache and doing a shut down then restart did not fix the problem. This has never happened before.

@Bettina-Löffler Thank you! Looking forward to it!

My tree of life has disappeared. It was there before I cleared my cache but has not reappeared since then. Is it gone for good?
