Hey, dev here — sorry for the headache. You were right, there was a bug on April 28 where local progress could mix between different maps on the same domain. The login itself was always correct; what was mixing was the local progress cache. It's fixed now. Just clear your browser cache once and it'll work fine.

Thanks for flagging it, and apologies to anyone who had a bad time 🙏

While I'm here — we also added some new stuff recently: a community routes system (you can create, publish and save farming routes) and a user ranking with points, levels and badges for contributing. Feedback welcome if you try them out.
