@tnt The "1 top level cell" thing is probably not explained properly by me: On some rare occasions customers would submit a GDS database that erroneously had something other than "user_project_wrapper", "openframe_project_wrapper", etc. in the file at the top level... in other words, they submitted two "chips" in one GDS file (though it was actually always an error due to finger-slips in probably Klayout that would "duplicate" a selected cell as separate junk at the top level). Tiny Tapeout has already passed the new tapeout job 🙂 I've asked David to double-check it first thing in the morning.
