Case 1: Just press the undo button and see the chat history vaporised.
Case 2: Send a message and Agent randomly dies.
Here’s a log from case 2:

I don’t have an error message for Case 1 since I thought it was just a one-time issue, but it turns out it’s recurrent. I will post more logs later.

I literally lost WEEKS of history and my new agent need to be rebriefed/context diving. If y’all think y’all losing money from Antigravity, this is the cause!
Instead of cutting quota, fix your IDE first, this rediscovering phase for agents is wasting my time and y’all compute.
