I lost the scenario and so I have no screenshot but I built a food processing plant in the Tropic Climate and that made fields. Sorry, but now I can't repeat the food plant bit in any climate.
a44 not affected
If I start and save the scenario in a44 and then load it into a45, the fields built in a44 remain in a45.
I'm going to try an a45 new game and see if the program makes fields. brb.
Ok ... I'm back ... Appears to be a randomizer issue ... With new game in all 3 climats I saw farms with no fields, I saw fields with no farms, I saw farms near fields but not amongst the fields and I saw fields around a fruit plantation but these may have been generated with a remote farm.
Definitely, in the lost scenario, building the food plant generated the fields.
