After updating pywikibot, my bot started ignoring existing archive counter and start from 1 with Latin digits instead. This is clearly a regression and causing a lot of issues in the wiki.
Example:
https://fa.wikipedia.org/w/index.php?title=%D8%A8%D8%AD%D8%AB_%DA%A9%D8%A7%D8%B1%D8%A8%D8%B1:Jeeputer&diff=prev&oldid=41869565
(The counter is reduced from 69 to 1 and instead of archiving to https://fa.wikipedia.org/wiki/%D8%A8%D8%AD%D8%AB_%DA%A9%D8%A7%D8%B1%D8%A8%D8%B1:Jeeputer/%D8%A8%D8%A7%DB%8C%DA%AF%D8%A7%D9%86%DB%8C_%DB%B6%DB%B9 (Persian digits: ۶۹), it started to archive to 1 in Latin digits: https://fa.wikipedia.org/wiki/%D8%A8%D8%AD%D8%AB_%DA%A9%D8%A7%D8%B1%D8%A8%D8%B1:Jeeputer/%D8%A8%D8%A7%DB%8C%DA%AF%D8%A7%D9%86%DB%8C_1
I remember fixing this long time ago
