The city node appears to have been missing for some time, even over a year? Possibly connected with its renaming. I’ve added it back with name =চট্টগ্রাম , but it is still missing most or all the original language names that it used to have. Achavi fails to recover these for me, maybe someone else will have better luck?
Also, is there there actually a space in চট্টগ্রাম or am I misreading it?
