Beta grid refresh?

I was just wondering - Do they refresh the beta grid on a regular basis? Last week I got on there and my inventory was from the beginning of the summer. When I got on today after the outage yesterday, my inventory (all of it, from what I can tell) was corrupted, so I have none of the tools I usually use for testing on there...

They refresh the beta grid when they need to, or when they feel like it. They are in the process of doing it now, and it should be ready by Tuesday. There's a new round of testing that will be starting up soon for server version 1.25.
