Nice to go over these and revert some of the deletions:
It might be easier to make a list of what still needs to be checked rather than what has been fixed? Perhaps I'll see if that can be done fairly easily.--Zenit (talk) 17:35, 10 May 2021 (CEST)
fixed: Leipzig ; check: Warsaw, Barcelona, Berlin, Bergen, Trondheim
2020-08 2020-09 fixed Tehran, check: many
2020-09 2020-10 fixed Vigo, Algeciras, Coimbra, Lahti, check: many
2021-01 2021-02 I'll check the Currents in this one--Zenit (talk) 13:56, 11 May 2021 (CEST) -- Edit: I'll check everything. Page 1 done :-)--Zenit (talk) 14:09, 11 May 2021 (CEST)
2021-02 2021-04 I finished checking all the "currents" on this one, rollbacked those where good and important information got deleted. Warlo (talk)
The ones marked as (current) are easier to handle.
If you have admin rights this may be easier because you can more easily roll back a bunch of edits.
Let guaka (talk) know if you want to help and you think it'll make it easier for you if you have admin rights.
