Regeneration In Process
Especially about Russia; I have absolutely no clue what happens with Russia for most of recorded history
I'm pretty hard-pressed to point out any single events in the 14th century myself, aside from the most obvious one in 1380.
Anyway, I'm sure that nothing important occurred from 1343 to 1350 in Russia. Muscovy and Lithuania steadily strengthened and expanded slightly, but probably nothing more. Certainly nothing that would matter in the Rice and Salt timeline.
