so this has happened to me several times and if it's a feature of the game the. It's a joke and I'll probably quit playing. This was the most recent episode...I saved up for the level 3 Academy, 425,000 left it to complete its ten hour build. Came back later to collect resources and sent out my ship to explore again probably 3 hours later, received notification I had been attacked and that my Academy had stopped building but it was still level two. My Grog was left at ~30,000. I'm furious as this keeps happening. It doesn't happen every time cuz last time I left a Grog storage to upgrade and was still building when I got back. Anyone else having this problem?!?
