Two days ago I put one Q1 food company at sale (it was assigned to my holding).
Initially I put some price that is not competitive, so I wanted to change it (through the Sell/Dissolve option), but that doesn't work - when I enter Sell company page I just see message saying "This building cannot be sold.", i.e. there is no usual option to change the price or withdraw company from sale.
I also tried to unassign company form the holding, but after that it even disappeared form market (previously I was able to see my offer)?!
In meantime, during last two days, I successfully sold other 5 companies (also Q1 food), using the same scenario.
This looks like some bug... What do you suggesting to do, guys, to "unlock" my company?
