This "2 day" rental thing is very worrying for me. I haven't waited a whole day yet but I've just started using this system and the rentals are spending double the DEC that I want to, and I have not got half the DEC back after cancelling the rent. (This also means I have less DEC to spend on rentals in total)

Do I get refunded after 1 day? Where is the 1000+ DEC that I spent being set aside?

Otherwise the autobid system seems to work very well, but it's sort of annoying how it makes manual rents pretty much impossible unless you overpay.
