Caravans are giving me a good amount of money and sometimes I have got +1000 daily from one of my caravans, but most of the times I get 300-600. I find the current income from caravans ok to be honest.
Concerning workshops, I have found some of them giving a good amount of money like Smithy in Seonon (250-300 daily). And I am now getting +100 from most of my workshops but I am still getting 50 from some others. I think the workshops have been just slightly overnerfed, but the current situation is much better IMO and makes more sense.
I just hope that equipment costs get fixed because the do not make sense at all currently, especially high tier equipment which is insanely inflated.
