I had success with a bus based base, but the bus only moves fruits, bioflux, spoilage and seeds (going backwards).
Along the bus every station makes an intermediate product and also produce the mash, jelly and nutrients it needs.
Everything that reaches the end of the bus is burned or thrown into ...

The Research progression tab, the one above minimap, disappeared.
Disabling all mods an resetting all setting to default did not solve the problem.

(I've research running)

Most recent Factorio version on most recent Mac OS, through Steam.

any help?

thanks
