i know what you mean, but its not like that. once over 35 offers used for any purposes (android on 6.6) buttons sometimes are not gray... but nothing happens, anywhere. unfortunately.
and directly to player does not show.

on 6.7 it goes gray at 25, but works trough players, but never quite had 35... 33 was most. think bastard counts gifts and training field bonus towards that maximum 35
